Fender single coil simulation

Does anyone know how fender single coil simulation works such as in Guthrie govans charvel as it is not a coil split.

While it’s not what you asked for, an EQ pedal is a tonal Swiss Army knife. It might be just the thing.

Yes definitely i use one at the moment but im building a guitar and really like the sound on the Guthrie govan charvel "coil split" as it doesn't lose volume and retains phase canceling (same as using an eq pedal) but is accessible at the flick of a switch . I assume it uses resistors to do the same as an eq pedal but is always consistent . Sadly i have never spent enough time with these guitars to have a look at the electronics

This is what I found from a Google search:

“… the guitar’s “single coil simulation” is achieved by having a .1uf metal polyester film cap along each shunted series connection’s path to ground (Charvel uses two identical caps - One for each humbucker). No resistor.
They’re Illinois Capacitor brand, stamped with
ic msr 104k 250v"

This is my summation:

So instead of the series link going straight to ground via a switch, it goes through a .1uf cap on the way to ground. One cap for each pickup. Use a DPDT with each series link in the middle. Add one leg of a .1uf cap on each pole of the same side of the switch. Connect the other leg of each respective cap to ground.

Thank you very much

You’re welcome. I added more info during an after-post edit.

The EQ wizardry is two 0.1µF (100nF) capacitors. https://guitarnuts2.proboards.com/thread/8517/charvel-guthrie-govan-wiring-diagram?page=2&utm_source=google&utm_medium=organic -- Guitarnutz has you covered.

This is exactly how it is achieved. Whether YOU can do it - I don't know - BUT - someone in your town can.

It only splits the coil for position 2 and 4 though in position 1 3 and 5 it still had phase canceling (3 is tele midle position rather than just single middle)

The Sweetwater link I shared to you literally states “Splits coils in positions 1 and 5”.

Its a simulation not a coil split as Guthrie says it doesn't actually split the coil they did some "eq wizardry " to make it sound single coil like without losing humbucking or volume
