I've got a 62 re-issue Jazz. Every time my fingers are in contact with the strings and moving it is producing a high frequency hissing, spitting, crackling sound. I'm assuming that it is the bass causing this because I've tried it through 2 different amps, 2 different cabs and I've changed all the leads. Amps and cabs are a Schroeder 1210L, BFM Omni10, MarkBass LMII and Ashdown ABM500 FWIW. Anyone got any ideas?
