I have a GK 1001 RB bass head. It blew out not too long ago, which made me angry, but it was under warranty... no biggie. Got it back, played it for 30 mins. and what do you know? It's dead again. Has anyone else had this happen? Also, how many times do I send it back before I can expect a new unit? I like this one, but not if it's gonna keep costing me $30 to send it to CA (from OH). When I bought this, I asked people what the most reliable bass amps were... what doesn't fail ever... and I heard GK. But now, I don't know if that's true.
