I got my 99 American Deluxe Jazz Bass january of this year and i must say, i love it. I got it used off of ebay for like $700 and it's a great bass. It's just now, i'm thinking it's sounding a little bit too active for me. Everything is stock. I've been reading the forums and from what i understand my pickups are pretty good. (?) i'd like to get a more vintage sound out of my bass though and was wondering what i should do to do that. i was thinkin probably active to passive and see how that works out, but i'm totally unsure on how to do that. could someone tell me how i might go about bypassing the preamp. or is it even worth it? for a vintage sound would i be better off just buying an old 60's or 70's jazz bass? or could it be done and easily switched back?
