so i think i decided that this summer i'm going to buy another jazz bass, but modify it to have a precision pickup at the neck position. and then get a pickguard from warmoth. anyway...i was thinking more about it, and i'm thinking i'm going to get a geddy lee jazz. can anyone think of any major problems i may run into with doing this? also...i know the necks are thinner on these than on the regular mia fenders...so if i later decided that i'd want a regular jazz neck...would a warmoth replacement be a direct fit?
