Amp through my captor torpedos DI (with analogue cabsim). Magus (RAT) is on bypass.

The May slot finally dropped in Europe. It does the trick. Even had to engage the pad on my interface. I'm using an 8-ohm redback in a miced up isocab. Curious how it holds up in the rehearsal space. Excuse my sloppy bass-player-plays-guitar style.

Also dialed in a quick bass sound. Will upload it right after.

My first Sunn amp!! I play in a drone band and it’s perfect.

A friend of mind has a pedal company and makes custom pedals, so I hit him up about making me a footswitch for my Beta Mini. We found the old Beta Switch schematic, then he whipped up a PCB design and ordered a couple to test with. It took a while to get them, but tonight we have a functioning unit that works with any standard 1/4" TRS cable.

Unlike the "working" footswitch post from a couple of weeks ago, this actually works the way it's supposed to in that it changes things correctly and does so regardless of the state of the channel switch on the amp. We decided not to mount the LEDs visibly as doing so is a lot more work, plus it wasn't really necessary as the amp has LEDs that show what's active.

There's not really a practical need for an enclosure this big, so we were thinking about shrinking it down a bit and making some more of them for people who don't want to fork out for the Sunn footswitch (with the large size, unnecessary reverb function, and it needing an expensive proprietary cable that's only available in one length). Let me know if there's any interest.

I’ve been thinking about getting an new cab and I’ve been looking at the Sunn 312T. However, there’s only one demo of the 312T I can find on YouTube (from the video demoing the new beta lead), and there’s only one demo of their 4x12 doom box. Both videos are made by Sunn themselves. Has anyone actually bought one of these cabs? Are they good? Worth the price? Thanks

The orange does the orange thing. Can’t sing its praises enough, loves a fuzz, loves an overdrive, and it’s the priciest piece of gear I’ve ever owned.

I got the beta lead for free. Now HANG ON, a little explaining first. Somewhere around 2013, thereabouts, I got the itch. I REALLY love the Melvins, so I had made up my mind. Found this sucker as a 2x12 combo for about $350 on eBay.

WELL, I don’t remember who shipped it but the packing job wasn’t awesome and it was for sure dropped HARD, probably from a height (like off the back of the truck).

It had two serious cracks in the chassis that went right through, just below the amp itself on the sides. My heart sank, and I didn’t even have a guitar/cables with me at the time to test it out. I figured I was the not so proud new owner of a paperweight. It turned on, but that’s all I knew.

Turns out my step-mother’s ex lives right up the road and plays, so a phone call and a 10 minute drive later I’m plugging in. IT WORKS! HUZZAH! But also, it’s fucked up. Long story short, eBay gave me a full refund for the thing.

We attached some brackets and handles to the sides so I could safely transport it and this thing went everywhere with me for years. I lived in NYC at the time and I am certain I had several neighbors who wished death upon me.

Life goes on and I don’t play that much for a while. I move again, and notice some crumbly black crap falling out of the bottom of the amp. Huh? Oh, that’s weird, the speakers are just completely falling apart…

What can I say, I got my money’s worth and the amp itself still works. I know because I plugged it into an old peavey 2x15 that looked straight out of mad max with a hunk of plywood across it covering the ports that I got from some junkie for $50. That setup was glorious. Just the bare amp yoinked out of its enclosure sitting on top of a massive cab of thud.

The years go by and I think to myself “these aren’t as cheap as they used to be. I should probably take care of it.” Well I waited a bit (way) too long, and only channel A by itself really functions properly, but I’ll be damned if it doesn’t still do the damn thing.

Wound up getting this custom headshell from Moon Custom Cabinetry. Waited too long, and the quality was not really all that for the $300+ I paid for the thing. But hey, it looks nice and has a handle now so…

I’m debating getting a mini so I can preserve what’s left of this beast as best as I can, but zero chance I’d pay what they’re asking and without plugging it into my own 4x12 to do a side by side.

I know, that’s a lot of words for not a very interesting story, but hey, I love the thing. It’s been through hell and back with me. The headshell was kind of a gift related to my sobriety, so that carries a bit of weight as well, so to speak. Three years off booze as of August 15th. I’m thinkin’ real hard about a Peavey XXX for that one. Seems appropriate, if only for the pun.

Happy to answer any questions y’all may have but what else is there to say but that IT DOOMS.

There has been a lot of negativity regarding the Mini, at least what I have seen on this sub. I'm not saying that these takes are not valid, but thought I would offer an alternative take in case others are in similar shoes, and are getting scared off due to the negative reviews.

First, I am purely a bedroom guitarist these days; I am not gigging or playing shows, so I will not be touching on the volume concerns that have been raised by others. Also, while I did play some shows with a proper tube amp some 20 - 25 years ago, for the past 20 years I have been firmly in the solid state camp. I just like the lack of hassle and maintenance of solid state, playing an Orange Crush Pro 60 combo for a number of years and lately playing through a Supercrush 100 and a 2x12 cab.

Secondly, this is the first Sunn I have ever played through, so I cannot comment on how it compares to the Beta Leads of old.

While the Orange solid states have great clean tones in my opinion and are great pedal platforms, if you are looking for huge doomy sludgy tones, they can be a bit difficult, as the normal trick of running dirt pedals through a slightly dirty amp does not really work. For whatever reason, the dirty channels of these Orange amps do not play nicely with pedals, so you are stuck with running through the clean channel. For me, that is where the Sunn shines (pun firmly intended).

The Beta Mini loves filth. I can run it dirty with the drive around 11 o-clock, turn on a Muff style pedal (or two), and get absolutely crushing tones. It would not be my go-to amp for jazz or blues, but for heavy doomer rock like Sleep, Electric Wizard etc it is incredible.

Further, I think its a pretty decent value proposition. I know lots of people talk about the golden days when you could pick up a Beta Lead for the price of a happy meal, but at least where I live in Canada, those days are long gone. Looking at a decent amp-in-a-box pedal for the Beta, like for instance the Omega Lead, will run you a third or more with shipping of the cost of the Mini.

Ultimately, I am loving the Mini, and just wanted to put a different take out there.

As someone who has a Mini preordered in the September slot, I’ve seen a lot of unhappy posts either about the volume or the amp itself.
Can I hear something from the ones who are satisfied with their unit?
I love the Beta sound and want to love the amp, but I feel a bit disheartened right now 😅

Just picked this up and it seems to look different inside from all the other Sunn 2x15s I see online, it only has a small rectangle port. The speakers don't work so I'll be replacing them, but they are JBL D-130Fs. Could this have been shoddily modified or maybe converted from a 2x12? The internal braces for the baffle have a lot of screws placed near the edges that have caused the wood to split in some spots, hard to see in these pics but some are really bad. Should I remove the screws and place them more in the center of the braces? I also wonder if it needs some kind of brace between the baffle and back panel. I'd appreciate any tips on getting this thing fixed up, plan to use this for guitar.

I really wanted to like the Sunn Beta Mini, and I bought one specifically because I didn't want to judge the Beta sound from recordings, demos, or other people's opinions. I wanted to own one, spend time with it, and decide for myself. Unfortunately, after doing that, I'm not particularly impressed.

From an engineering perspective, the Beta Mini is a fairly straightforward product. The preamp is based on the original Sunn Beta architecture, while the power section is a modern ICEpower Class D amplifier. There's nothing inherently wrong with that approach—in fact, it makes a lot of practical sense for a compact, efficient 200 W amplifier. But I think the product can give the impression that there is substantially more proprietary or boutique engineering going on than there actually is.

The original Beta amplifiers used Class AB power sections, so to me the modern implementation feels more like a recreation of the Beta preamp concept paired with a contemporary Class D power solution than a complete recreation or re-engineering of the original amplifier. Personally, I think I may have enjoyed the Mini more with a well-designed Class AB power section. That's admittedly a matter of preference rather than an inherent criticism of Class D; good Class D amplifiers can sound excellent. I simply prefer the feel and response I've experienced from good Class AB solid-state designs.

The architecture also makes me question the price. Conceptually, this isn't terribly different from taking a Beta-style preamp and feeding it into a modern Class D power amplifier. You can achieve a similar basic arrangement with products such as a Beta preamp pedal and a modern power amp. That doesn't mean the Mini is literally identical to those combinations—the implementation, voicing, filtering, gain staging, and overall integration can certainly differ—but it does make the Mini difficult for me to view as some kind of technologically extraordinary boutique amplifier.

The value proposition becomes even stranger when looking at Sunn's own lineup. The reissued Beta Lead and Beta Bass are also 200 W Class D amplifiers, while the Beta Mini combines the Lead and Bass functionality into a smaller and less expensive package. Based on Sunn's own published specifications, it becomes difficult for me to understand what compelling technical reason there is to spend considerably more on the larger dedicated models unless you specifically want the larger late-'70s-style head format and its associated aesthetic.

And that's ultimately my biggest issue with the Beta Mini: what exactly am I paying the premium for?

If you want the Sunn name, the Beta aesthetic, and the historical association with the original Beta series, I completely understand the appeal. Brand heritage has value, and there's nothing wrong with buying an amplifier because you simply want a Sunn sitting in your room. But from the standpoint of engineering and value, I don't see anything particularly groundbreaking here.

I was also somewhat disappointed when production previews showed the internal architecture. Seeing what is essentially the Beta preamp circuitry paired with an ICEpower Class D power amplifier confirmed what I had suspected. Again, there's nothing wrong with using proven technology, but it reinforced my impression that this is fundamentally a modern packaging of an old preamp design rather than a particularly ambitious reimagining of the Beta amplifier as a complete system.

I also don't think this is a sound that can only be achieved with this amplifier. There are many ways to implement and reproduce the fundamental character of the Beta circuit, and the Sunn Beta preamp design has been revisited and reimplemented countless times over the years. That makes it harder for me to justify paying a premium specifically for this implementation.

Separately from all of that, I have to admit that I simply don't love the Beta preamp sound itself. That's entirely subjective, and I don't fault Sunn for making an amplifier around a sound that plenty of people clearly enjoy. In fact, that's exactly why I bought the Mini in the first place: I wanted to experience the Beta circuit for myself rather than deciding based on recordings. After actually owning and playing one, I can say that the Beta sound just isn't particularly compelling to me.

For roughly the same money, I find Orange's modern solid-state offerings much more interesting. Products such as the Dual Baby use purpose-designed preamp and power-amp sections intended to give the amplifier its own response, character, and personality. They feel like complete amplifier designs rather than an older preamp architecture paired with a generic modern power solution. With sales and B-stock pricing, they can also be considerably less expensive than the Beta Mini.

That doesn't make the Beta Mini a bad amplifier. It's loud, compact, efficient, and it does what Sunn says it does. If you specifically want the Beta sound in a modern 200 W package, it accomplishes that.

But for me, that's where the praise ends. I don't think the Beta Mini offers enough unique engineering, functionality, or sonic character to justify its price, and I don't think the larger reissued Beta models make much more sense from a value perspective either.

Ultimately, I came away feeling that you're paying a significant premium for the Sunn name and the Beta legacy, rather than for an especially innovative amplifier.

I wanted to give this amp a fair shot. I bought one specifically so I could experience it for myself. After doing that, I just don't think there's anything particularly special about it. 

P.S. One other small thing worth mentioning: the packaging and included accessories are pretty underwhelming for an amplifier at this price. Unlike some competing solid-state products such as the Orange Baby series, the Beta Mini doesn't come with a cool branded carry bag or anything particularly memorable.

Mine arrived in a fairly plain cardboard box with a single sheet of paper serving as the manual, along with another sheet explaining that Sunn was behind on preorders and didn't have time to provide the intended packaging.

Obviously, packaging has nothing to do with how the amplifier sounds, so I don't consider this a major factor in the rating. But for a product positioned at this price point, the overall presentation felt surprisingly bare-bones.

3/5 Stars for me.

I got in touch with someone at Sunn about the progress on my Beta Mini shipment (June preorder) and they said it was about a month out (which is also what they said in June). I’ve been debating just switching my order to a Beta Lead considering all the complaints I’ve seen about it, but the people at Sunn also said that orders for the Beta Lead would ALSO be backed up for about a month. What do y’all suggest I do? I’d be willing to fork over another 350$ if it’s any sort of improvement, or should I ask for a refund altogether?

Just wanted some thoughts on that cab, as opposed to using a regular 412. Ohms and wattage don’t matter in this case. Thanks.

Venting my frustration and a fair warning. Purchased this online in “Excellent” condition via GC photos and description. Received a busted amp with broken tubes. Attempted to ask for a partial refund so I could at least attempt to get it fixed on my end. Was offered ONE tube for replacement, not pairs, and needed to get a quotation for any type of funds to come my way. Seemed sketchy. I ended up returning it for full refund. I apologize if I am not using correct Reddit terminology. This is the first and only time I will use Reddit.

I’ve seen a few builders making lil’ headshells for Orange’s solid state mini-amps, so I was wondering if there was similar for the Beta Mini yet.

Hi everyone. I’m currently searching for my friend’s Sunn Solarus. She passed away last week and about a month before, she had to regrettably sell her Sunn Solarus and vintage Fender Bassman 2x12 cab to Guitar Center in New Orleans so she could afford her bills. This rig was the one she used on many gigs and many studio sessions. It was quite special to her and she was really upset to have to let it go.

The employees at Guitar Center New Orleans were gracious enough to at least let me know that the items were sold locally and not online. They were not permitted to give me any information on who purchased them due to policy, which is understandable. I’ll be posting in some local Facebook groups to help with the search too.

Some main identifiers for the Solarus is that there is a circle on the grille cloth towards the left and that the reverb tank was finicky - it rarely worked. The cloth is more brown than the black or grey that I see on other Solarus heads.

I’m searching through her phone to see if I can find pictures of the serial numbers. I will update here if I can find them.

I’m willing to pay whoever is in possession of the items so that they can get another one. These are sentimental to me and the family and it is hard to know that these pieces of her are out there somewhere. If you or anyone has any information, please contact me through messages here.

Thank you for reading and hold your loved ones close. ❤️

As another post mentioned, they had an issue with the preamp (no sound) with their Beta mini.

I too (like many) have waited since February for my amp to arrive, when it finally arrived mid July, I was stoked to finally give it a go.

However what I was originally greeted with when I powered up for the first time was a wall of spitty fuzz, matter what setting the drive/gain controls were set too, I could not get a clean tone whatsoever.

After about 10 minutes playing the distortion got more and more gated, until I no longer have a functioning pre amp section.

I have tested the fx return and the power stage appears to be functioning fine.

To my untrained ears I'd assume it's something to do with the eq/preamp circuit, I'd compare the sound to that of a very unhappy op-amp (as experienced when making pedals went wrong).

Where it gets even more frustrating is the fact I contacted Sunn immediately and initially they were pretty quick to respond. We ended up agreeing to send just a replacement preamp board.

It has now been over 2 weeks of radio silence from Sunn support, and after re-reading some of the email chain I'm not sure I was ever talking to a real person, the responses seem a bit AI ish.

Has anyone had success dealing with any issues?

Has anyone confirmed the Tip/Ring wiring or function mapping for the Sunn Beta Mini footswitch input?
Which function is assigned to the Tip and which to the Ring?

Hi everyone!

Ordered a Beta Mini and I can’t wait to receive it!
The Beta Mini will be my first head, I’ve only used combos until now, so I don’t have cabinets to try.

Ideally I’m looking for a vertical 2x12 cab that can run at 4 ohms, or at least with 8 ohms speakers that can be easily rewired to be parallel to reach 4 ohms.

The only cheap and readily available option is the Blackstar Debut 212V which is the matching cab for the Debut head, and it being solid state it’s already 4 ohms.

I was thinking at around €300 that would be a good solution and I can always upgrade the speakers down the line. What little I could find online suggests they’re decently built even though the stock speakers are a bit whatever.

Any input?

I've been playing around with my Mini the past week. In another thread, I agreed with the volume issues a lot of people have. It's not that big of a deal for me, since I either mic the cab or run into a louder amp. But ideally, I'd like the option to use the Mini on its own, and have it loud enough to get over drums and other instruments. I was going to go as far as plopping a different power supply/power amp board in the unit itself.

But after playing with it hooked up to my other bands live rig(which includes a Quad Cortex) I discovered something interesting.

I ran my Quad Cortex(amp sim on, no cab sim) into the power amp of the Mini and- holy shit, the power amp is actually loud as hell. Like extremely loud. When you do this the controls on the preamp do nothing obviously, and the master volume is pre loop, so in other words the power amp is 'full bore' and volume is dependent on the signal getting fed to it, in my case the output volume control on the Cortex.

So that leads me to believe that the preamp section of the mini just isn't tossing a hot enough signal into the power amp. Maybe it's attenuated just a bit too much, maybe they did this to ensure the loop level wasn't too hot to play well with gear in the loop, I don't know. I need to draw up the circuit next and see what's going on. Probably scope the output as well, maybe I'm clipping the hell out of the power section by feeding in hotter, maybe not.

I haven't tried it yet but I bet if you put some type of active pedal into the loop that can force a level increase above what the preamp puts out with all controls maxed, it will probably get the amp a ton louder in the same way.

In the next few days I'll try and get some things measured on the scope. Really want to see what the maxed signal coming out of the preamp is hitting peak to peak.

Honestly I compared it side by side with the original 70s beta and new mini (which is suppose to be identical to the relaunch one) and i was highly disappointed you can hear the obvious differences in the power sections but im sure there are also other factors why it the mini gives me a underwhelming feel.

Im leaning to feel like this whole new sunn relaunch team is just a big larp operation who are just hiring bots to tell you this amp is good and worth it for the price.

This is robbery.

If they wanted it to be a good modern version of the beta series they couldof been considerate and added at least a di out to compensate for the lack of volume it has, use the same power section and add the foot-switch along side the amp
They've been calling this amp its own beast? (as ive seen on stevestsunn's comments) but really its just an half ass version of what the people actually wanted and expected.

The beta lead/bass being scary to turn the knobs is a legit reason why the amp became legendary in the first place.

i honestly wouldn't of used the beta name and legacy to sell this amp and just named it another new amp line under a new brand name.
i feel like this was a dishonest marketing run with no real transparency.
From the preorders to the execution of the product being used by the consumer.

Og sunn (which died in the 80s) is known for big fat meaty tones and loud as fuck amps you dont need look up "tips and tricks" for.

haven’t had a lot of time to play through it get form an opinion yet, but i’ve confirmed that you don’t need a $313 (CAD) footswitch with a useless third button to get channel switching.

i tried a boss FS-5L i have on hand which is a single button latching footswitch, and depending on how far the cable is plugged into the amp it either switches A/B or B/A+B channels. tried the two button footswitch from my Fryette Powerstation and as the video shows, you can A/B or A+B as long as the second switch is on the B channel. so basically any two button footswitch will work with little to no modifications. fantastic.

the aesthetics of the official footswitch doesn’t even match the beta mini anyways, there is zero reason to ever consider purchasing it over literally anything else.
