I bought an SBK-3AD preamp from Tone Monster. I've attached the wiring diagram. I want to replace the treble/bass stack with two separate controls. I asked the seller (Guitar Fuel) and they suggested I just buy another preamp from them (so helpful!). Could I just buy two 50k pots and wire them separately the same way the stacked one is?
Sure you could, just make sure to get the wires/pins right. I'd check the existing pot with a meter to make sure what's left pin, right pin, and wiper pin.
