Anybody know anything about this brand of amps? I just recently picked up bass, and my friend let me borrow his amp. It's a Garnet Minibass amp, with a 12" speaker. I took it to practice with my band, and when I turned it up, it started rattling on the lower notes. My guess is the tubes are bad. But nobody at Guitar Center knows anything about the amps, and Google and garnetamps.com hasn't helped at all. Basically, my problem is that I donno what kind of tubes it needs.
