I bought a used Geddy Jazz last year and in a live situation, I found that I'm not a fan, at all, of the V/V/T control layout. I have decided to change the controls. After reading many threads on this subject, I have learned alot, but there is alot of conflicting information and opinion in regards to the subject of adding a passive blend. My question is... I think i would prefer having a stacked V-V to control the blending of the pickups and then have a master volume knob, and then tone. Is there any glaring advantage or disadvantage tone-wise doing V-V/M/T vs the more common V/B/T setup? Also would it be feasible to add a 3way pickup selector swtch (front/both/ rear) between a stacked V-V and master pots? The master volume control is important to me for swells and such, not just for cutting volume between songs.... not a fan of vol pedals for this. Thanks!
