I brought a Tele with Kinman ""noiseless"" pickups into 30th St guitars for a new toggle switch. The pickups are about 2 years old and have indeed been free of hum since they day I installed them. When I picked up my guitar from 30th St, the new switch was in, but the guitar had hum. I went back to the shop a couple days later and was told that the repair tech/owner was out for a week, but they had another tech coming in the next day.\r
Tech #2 said he couldn't hear any hum and said he'd stake his reputation on it. We plugged it in and, sure enough, there was plenty of hum and tech #2 looked embarrassed while the guy behind the counter laughed at him and his ""reputation."" Tech #2 advised me to come back when tech #1, the owner, was back the following week.\r
Today, as instructed, I went back and saw Matt, the owner, tech #1. He said there was no way anything he did caused the problem. I pointed out that the guitar was whisper quiet until I left it at his shop. I protested that I had been back and forth 4 times, and was frustrated that the other tech initially denied even hearing the hum. His response was that he was away so couldn't answer for that. He said ""it wasn't me"" and that something was wrong with the pickups.\r
Whatever happened, it happened on his watch -- he's the owner and ""I'm not accountable for what happened while I was away"" doesn't cut it. He made no offer to repair the guitar, or even explain the coincidence that my pickups started humming exactly when he worked on the guitar.\r
I said I would bring it someplace else and that I wanted my money back. He had the nerve to say, ""Ok, give me back the toggle switch and I'll put your old one back in."" I swore at that point. Matt was unwilling to discuss it further after that. I guess it's fine for him to give me my guitar worse than when it came in, and it's fine for him to nickel and dime a customer who has come back again and again in good faith; but heaven forbid the customer should lose his temper.
