Alternate Wiring Layouts for 4001 or 4003 Bass

Just wanted to point out (if it has already been done, apologies) that you'll need a preamp to do Treble and Bass controls. Otherwise there's nothing wrong with master vol + blend. I would recommend pretty high resistance on the blend pot. For the other two slots if you stay passive I'd use one as a regular tone control and the other as a rotary switch (can look the same on the surface) for selecting different capacitors for the tone pot, so you have a two knob varitone setup. Could be lots of fun.

I'd use a 500 K master vol, 1 M blend, and 250 K tone with the rotary switch for the cap. But that's just me. I'm very sold on the use of low resistance for the tone pot as long as you have capacitor values that you actually like, usually people make the mistake of going too big.

The master vol will definitely cause you to lose stereo but you could convert to a dual mono setup. I did that on my 4001FL and it works fine, though I've never thought of a clever way to use it. I guess it prevents those "Hey! My neck pickup broke!" freakouts...

Assuming I do this, has anyone thought of a legitimate use for the pickup switch? It's superfluous with a blend pot, but I don't want to change the look of the pickguard. Maybe just leave it as a dummy for show? If these were humbuckers, I suppose it could be some kind of coil tap switch, but these are stock hi-gains.

You can always leave it in place to rapidly kill off one pickup or the other. It would need to be wired upstream of the master vol, just like it is upstream of the individual volume controls in the stock harness.
