Dear all, this is my very first post, so thanks in advance for letting me in :) I recently bought my first sg, it's a 1970 special with short vibrola maestro. The guitar sounds really good, is a very resonant instrument, I've always been a 335/330 kind of guy but I have to admit that this is the ultimate rocknroll machine! p90 just scream! While I was playing I noticed a weird crackle when the vibrola is pulled up or pushed down, like a ground issue. I checked the cavity and the ground wire from pots to the wraparound is fine, but I was thinking if I have to do the same with vibrola. I know this is doable with lyre vibrola on sg standards, but what's the solution for specials? There's no holes to allow the wire through the body. has anybody ever had this kind of issue? Thanks again!
