I had a chat with him about defretting a bass a while back. He didn't tell me what I wanted to hear, but he did go to the trouble of explaining, in some depth, why it wasn't a good idea with that particular bass. He impressed me enough that I'm probably going to ask him to take a look at one of my skinny stringers in the next couple of weeks. I don't mind paying a bit extra for someone who really knows what they're doing.
