I just got a GK MB 212 and it's kinda noisy. Not noisy like the Carvin MB115 I had was (crackling with radio signals)... but just sort of a whooshy background noise.... and very loud single cycle hum on my J basses... My friend Dave said that it might just be that digital amps are noisy with active basses. I've never had this problem with any of my older amps and my Genz Benz Streamliner is perfectly quiet. So I dunno if I am going to keep the MB212...Musician's Friend gave me a killer deal but I can still send it back (eating the cost of shipping, oh well.) I was considering a Markbass 210... lower wattage but it does tilt back which I like. Some people say Markbass makes great heads but crummy cabs/combos. Other people love them unconditionally. The 210 tiltback (CMD 102P) seems to get consistently good reviews. Thoughts? Am I just crazy? I need a lightweight analog combo...300 watts or more!
