Bought a 60's reissue Jazz used. Nice Mexi bass. Very nice neck, very nice finish, nice pickguard, and very noisy when the tone pot is all the way up at idle. For reference, I also have a 99 MIA Jazz, clear ash that is the standard by which I judge all others. This one will probably never leave the stable. When comparing the two basses, the MIA is extremely quiet regardless of where the tone pot is set. The Mexi is loud requiring your fingers be on the strings to keep the noise down. So, as any good bass player should do, I start by replacing the pickups on the Mexi with pickups out of a 97 model MIA jazz to try and acheive that same quiet. The noise is still there. Perhaps somewhat more quiet, but possibly because I think it should be more quiet because I spent money for pickups. Nonetheless, it does not approach the MIA as far as being quiet at idle. Anyone have experience with replacing tone pots? Looked in the archives and see volumes of data on pickups, but very little on the controls on the plate. Or other areas I should be considering? Wiring, grounding, voodoo spells perhaps? I really like the sound I get out of my MIA Jazz and am not looking for a different sound, just trying to replicate the quiet at idle sound in the Mexi. Any thoughts appreciated!
