Followup for what it's worth: Posted a thread inquiring if anybody had experience with tone pots that were wired interactive (got dropped cause no response). I wired a bass passive with vol/tone vol/tone per Les Paul diagram except with a 3 - way coil split switch (pair HBs) and the volumes were independent but tones affected each and each volume - which would be both useless and irritating if the tones had the same size capcitors or if they interacted in a way where you just ended up with an average of the two capacitors. But it sounded like there were blending. One capacitor is a 104 and the other a 47. In having played with the thing a little more, the tones are indeed blending. You can actually tell the difference in tone created by these two different capacitor values by turning one off and maxing the other then doing the reverse. Plus you get all the possibilities in between. Crisp hi's to mellow lows. In terms of tone, this bass will walk all over a standard Bart NTMB unit w/mid switch - cause I'd just pulled one out of it. I don't know of any bass that's set up this way but it's not a bad way to go - unless you don't like many options. But it's no more control manipulaton to get a tone than with adjusting two volumes cause you tend to leave one tone set and adjust the other. I was suprised nobody has experienced this or had comment. But it definetly strikes me as something useful.
