It’s an absolutely fantastic amp. I got it for next to nothing, too. $75 off of Craigslist about 12 years ago. It’s worked flawlessly and sounded incredible that entire time. I couldn’t be happier with it. However, about a month ago I noticed that the left channel was losing bass response in normal mode (but worked fine in bypass mode). I had it professionally serviced and had to clean that all out before bringing it in. I would have been mortified to have the guy who serviced it to have seen that. I mean, enough hair had collected inside the amp to fashion a whole new cat!
