What's up everyone? First time posting, I have a question about preamps. I have a 2012 Fender P-bass special. (Seafoam green. So hot.) It has a master volume, blend between the p/j pickups, stacked bass and treble, and then a mid control. I never use the mid control. What would be the best preamp (2-band) to wire to the stacked pot? I also want to install a passive/active switch and make the existing mid pot a passive tone control. I have never tampered with any electronics in my basses, so I need some advice. Also, I really like the idea of Audere's z-mode switch. Could I install something like it on my bass? Thanks in advance!
