this is the earliest one I can find that has the filters wired to be on all the time
Mica,
I'm trying to follow wires, but I'm confused. Do the Filter Freq & Q knobs sweep each pickup simultaneously? Or is the signal summed and run thru the filter parallel to the direct signal?
You're referring to the circuit in the plural, but I'd imagine you'd need quadruple stacked pots to pull off my first guess?!???!?
