Could someone with a vol/tone vol/tone Jazz bass do me a huge favor?

Wait, what? Whoever heard of a V/T/V/T Jazz? Secondly, are you trying to find out whether you should mod your bass with a second tone pot or something? Maybe spell out your intentions, you might get some helpful responses that way. Even if somebody does have a V/T/V/T Jazz, what are they going to say? "Sounds OK to me." Will you base a planned mod on that?

 

I assume the OP is talking about dual stacked V/T pots as on my '62 RI.

I don't have my amp handy right now, but I've used settings "similar" to to one you describe. It sounds, um, ... good. But so much depends on your playing technique, your pickups, your strings, your ears, the amp, the room, the rest of the band, etc.

If I had to characterize the setting, it would be sort of a thicker, more-modern take on Jaco's sound on his self-titled album. Like on "Come on, Come Over". Sort of.

Are you thinking of rewiring your bass based on other people's verbal descriptions? Personally, I don't think the dual tone controls add much to the tonal palette, but ymmv.

 

You could get that setting by running the neck pickup from its volume directly to the jack, bypassing any tone control (that will keep the neck at full tone) and then just wire a capacitor inline from the bridge volume directly to the jack, that will be the equivalent of keeping the bridge pickup always at zero. You can then put your mute switch into the tone pot hole.

Or you can leave the tone pot in place, have it connected only to the bridge pickup (for adjustability later) and use a push/pull pot in place of one of them in order to make a mute switch...

 

How about a stacked tone/tone pot, for adjustability, and a push/pull volume for the mute?

 

Hmm, that's a good idea, makes me want to modify my Jazz electronics yet again...

 

Hell, if I get the parts, I might try it myself!
