Does your GK MB200 hiss?

Mine hisses a little bit when the treble is at noon and the tweeter in my cab is on. I don't hear it when (1) I play, (2) the treble is below 10 o'clock, or (3) the tweeter is off.

I read a for-sale ad here at TB where the seller said he had received a non-hiss version directly from GK. So, I wonder if a slight hiss is normal.

Mine hisses even with gain at 0

Mine does not - not that I have noticed (three rehearsals, has worked like a champ - and very quiet).

Every piece of GK gear I've ever owned has hissed. But it's never made a bit of difference to me once I start playing.

mine is dead quiet , no hiss what so ever . Even cranked to 1:00 which is God awful loud in the apt and tweeter full on there was no hiss ( Schroeder mini 12 ), there was however what I would call a normal treble noise at that setting and I would never use it like that but I'd say nope , no hiss . I have plans to track a jam later today so we'll see what happens there . IME different tweeters are more or less noisey so perhaps it's the tweet.

Mine starts hissing (not a loud, annoying hiss) when the red light turns blue, with gain at 0 and doesn't depend on the eq.
I don't know if its worth getting it repaired, even if I'm in warranty period.

I had what I thought was hiss but seems to have just been more treble than I was used to. SSCBA - IMO it's worth it to have them take a look before it drives you nuts and it's out of warranty. But that's just me.

I listened again and noticed a bit of hum too. Maybe I'm having grounding issues

I spent a good bit of time with the DI this weekend and conclude it's excellent ! No noise of any kind . In "post" mode it's gain dependent and can be boosted but but still noise free . So it seems GK some of your MB's may be noisey and if that lilttle bug was ironed out these amps as a whole could be the greatest thing ever , since sliced bread of course . With what little time I have spent messing around with electronics I know it could be any one of those components causing the noise or even be routing of wires within but some are dead quiet and simply fantastic amps .

I love G-K. Been playing them for well over twenty years, but I have noticed that some (including mine) are hissier than some other brands. Never been a problem though, either live, or in studio, either miced, or through DI..

Dead quiet. No hiss at all. Running through GK Neo cabs.
