Hissing should be an Issue for me if it's not excessively loud. I am in the market for a new bass cab and I was looking at the gallien-krueger mbe410 bass cab. I've read some good things about this bass cab. I don't think I've read anything about this cab having hissing issues except for the mbe210 and the mbe115. I was thinking of getting the fender rumble 410 bass cab, but I was informed that it's a 4-ohm bass cab and I needed an 8-ohm bass cab and so far the mbe410 is probably just what I've been looking for.
I have no problem with it. Someone mentioned it's more prevalent with active basses, but that's one opinion (and it could be partly due to his pickups). Who knows if these people have messed around enough with the EG/bass settings anyway.
Got mine 3 months ago. Great choice!
It would be nice if more posted on this cab,....but most here seem to have the more expensive 410 NEO'S.
