Serious 60 cycle hum on the bridge pickup. Didn't notice it in the store, but its really there on my amp at home. The neck pickup on the other hand is dead quiet (As is my Musicman so its not the amp). Just a question of grounding/shielding you think? If so, its a bit annoying but it's fixable. I drove about 2 hours to Chicago to buy it so even returning it is a PITA.
