Installing new pickups and need to figure how to add a passive tone pot.

[Nighthound]

I have a Vanquish 69 that I will be installing a set of Aguilar Super Doubles.

Right now I have a volume pot, pickup blender pot, concentric pot with mid boost and shape, and concentric pot with bass and treble cut and boosts. Is there anything I can do without adding another knob?

I hate not having a passive tone pot. Is it possible to disconnect one of the active eq pots and turn it into a passive tone pot? Should I just abandon the active circuit completely or maybe look into a two band module?

It's entirely possible to add a passive tone to a preamp circuit. If you want to keep those EQ controls, I'd suggest getting a stacked pot for volume and tone.

So your control scheme would then be: Volume/Passive tone stacked, pickup blend, mid/midFreq stacked, bass/treble stacked.

No need to drill new holes.

But my volume is right now is a push pull that disengages the active circuit. So do they make a PushPull stacked pot for volume tone and to disengage/engage preamp?

Maybe I can add a mini toggle to disengage/engage active circuit and just get the stacked volume and tone pot?

Hmmmmm. Yeah. You've got a while to wait on those pickups. For now, ponder the options you have.

Is there an appreciable tone difference between the preamp off and the preamp on with flat EQ?

I only appreciated the preamp because the low b wasn't as punchy and big as I wanted it to sound. Once I get the new pickups in, I'm hoping I don't even need to use the preamp circuit to give me the punch and bass I wanted out of the low B string, but being that it has the knobs and battery cavities already I figured it would be nice to keep the preamp.

Then you definitely have the option to tuck an unused knob inside the control cavity. You could replace either the mid stack or the bass/treble stack with a passive tone control, and leave the unused potentiometer centered and tucked in the cavity. No mods to the exterior of the instrument, apart from changing a stacked knob to a single.
