Hi there. I'm new to the boards(Just signed up to ask this), but I've kinda been browsing around for a while now...friend of mine told me about this place. Anyway...I've got a mexican Jazz bass that I use as my main axe, some may call it blasphemy but I'm considering dropping a Kahler Tremolo bridge onto it, but what I need most is a thinner neck. See, I've got relatively small hands, and I'd like to be able to play fast slap riffs without my fret hand aching within a few seconds.... I don't want to have to cut into the bass any, so it'd have to be one that can just drop right onto a Jazz...I just can't seem to find one any thinner than the one it's got...any help?
