MM pickup too loud? Probably wired in series. maybe you don't need to change the pickup, maybe all it needs is exchanging the places of 2 wires!
That's exactly what I wanted to ask....I got a P-MM on which I managed to get the same volume from the two pu's , by leveling their heights. What I would like to know is if the MM pu comes wired in series from the manufacturer. I suspect that because it's got a lot of mids, while a classic MM pu should sound a little hollow when parallel wired.
Other than that the bass is very well-manufactured , and with some minor mods (like lighter tuners) it can be a winner.
P.S. : just my two cents on the (cheap) preamp: I found on mine that backing off a little both treble and bass controls makes the output and tone comparable to passive. On the center detent volume gets sensibly higher, making it difficult to switch back and forth during the same song.
