Hello, I have Squier Telebass (officially a Precision) which has the mudbucker at the neck but an added MM at the bridge. All wiring is passive. The neck on this bass is really lovely. I am comparing it against a jazz bass with stock wiring, and it would be nice to have more of an overlap in sounds to allow them to back each other up if possible, although a wide tonal palette from each also has its attraction. At the moment both pickups have 500k pots on, ditto for tone with a 0.22 capacitor. These may or may not be the optimal values as blending the pickups seems to be more an on-off affair, and the tone control isn't very effective. I have added series-parallel switches for each pickup, and this takes some of the mud out of the mudbucker, and some of the midrange out of the MM, but would I get more crossover with the jazz by changing that for series-parallel-single (inner coils)? And should I consider changing the pot or capacitor values to improve operation? Or am I on a highway to nothing and should I treat the Tele and Jazz as their own things and get as close as I can to matching them for backup purposes (output volume and sound) with an EQ pedal at the head of the signal chain? Modes that are closest are Jazz (middle) compared to Telebass (both) and Jazz (both) to Telebass (bridge, parallel).
