Would it be possible to solder a treble bleed in a vvt jazz bass with a series/parallel push/pull pot to work only in series, and not in parallel?
If not, would a jazz bass still retain a vintage sound with treble bleed on both volume pots in parallel when - for example- neck pickup is on full and bridge is at 75%? Or would it have a more modern sound that way?
Hope this makes sense.:oops:

Have you already seen my 302 pages bass wiring pdf file (4.33MB - at the bottom of the linked site): http://161589.homepagemodules.de/t29f2-Cadfaels-kleine-Schaltplan-Sammlung-fuer-passive-E-Baesse.html
Only in German, but you might understand as well ...
I don't exactly know what you mean by "treble bleed" ...
On page 193 (drawing 2.1.01) you find a "normal" series/parallel wiring.
If the treble bleed works like a normal tone pot (parallel between ground and hot), you can try something. The switch has a "bridge" for series/parallel wiring. Solder one end of the tone pot to ground (like normal) and the other end not to HOT, but to this "bridge" on the switch!
The tone pot will only be parallel to the bridge PU but as both PUs are parallel then, it should effect on the whole sound.
In parallel mode, the bridge is not connected to anything and so the "hot end" of the tone pot has no more connection to the rest of the system ...

I already have the push/pull knob installed.
A "treble bleed mod" is when you connect a capacitor and a resistor parallel to each other and solder them to the ungrounded terminals on a volume pot. By doing this, turning the volume knob down doesn't muddy the tone, so it keeps a consistent tone no matter what volume you have it on.

Ah! I see. Something like in the 70s Telecaster guitars (there only with capacitors).
I think this won't work with a push/pull pot ...
In series modes ony the "neck volume" works?
As the treble bleed is between the to "HOTs", you wouls need a seperate/third "layer" (levels???) on the switch to cut the connection in parallel mode.
None of the existing two "layers" can be used because there is no connection to one of the "neck HOTs" ...
If you solder the treble bleed only to the neck volume pot, it will at least only work for the neck pickup or in series mode but not for the bridge pickup alone ...
