I gave Atlas Audio Repair my Fender tube amp when it started giving me trouble on tour. I paid the $40 evaluation deposit, and asked to speak with the technician. The man at the counter said he was busy and would pass on any information to the amp tech. I said that would be fine, but we agreed that before any work was done to the amp, the tech would give me a phone call to discuss the work and estimate.
Three hours later I received a phone call notifying me that the amp had been repaired. A speaker cable had come loose, the friendly amp tech said, and he had simply re-soldered it. When I asked how much it would cost, he said he didn't handle the money side of things, and handed me to the man back at the desk. He wanted $170, and when I expressed my surprise at the fee, he exploded in a rage, saying I could come by and pick it up after they had "un-done" their work.
A few minutes later I got a call from the owner, who began the conversation calmly, but soon exploded in his own right, calling me a "prick." When I mentioned our prior agreement -- that I would have to agree to any work beforehand -- he admitted that we had had the conversation, but said that I didn't understand electronics, and began ranting about his years of experience. Finally he told me to come by in an hour, because it would take that long to undo the repair.
Fearing that he might sabotage my amp, I swung by with the band right away and got my amp back. Running a soldering iron off our car battery, I performed the "$170" repair in a minute and a half on the city street outside of Atlas. (We returned a screwdriver they had left in the back of the amp).
Back in California, one of the world's finest amp techs would have charged us $20-40. If Atlas had held up their end of the agreement, they would be in the same boat, minus this shitty review. Do not take your electronics to this over-priced nuthouse.
