I was in a bind because I had a gig on Friday and my main bass amp's (GK1001RB) power transistors had failed the previous Sunday at practice. I went to Jim and he diagnosed my amp for free! I knew I wasn't going to be able to get anything fixed before the gig so he offered to loan me an amp! He ended up making me a SCREAMING deal on a used Eden stack that I've now fallen in love with. It was so cheap he made me agree not to tell anyone the price. Thanks, Advanced Guitar!
