Well it is a POS but it's my first bass amp, a Kustom 50 combo. It's had one 15" and makes a better bench than amp but it's sitting in my father garage and now that I'm playing again ... What's wrong, besides its fart-like tones, is that it hums like crazy. Maybe buzzes is a better description. I don't know what's wrong with it but figure just having it looked at will cost me $100. Now i have an AMpeg Rocket 100 thats fine for my purposes. But maybe a line a out to another amp, even this one, would amp some depth. Or since my band practices in my basement, we could use it as a guitar amp. Any guesses on what's causing the loud hum/buzz and how much it would run me? THankS!
