One one of my heads, it was a constant, low volume crackling and sometimes sort of thumping sound, as if there were a bad connection somewhere. On the other head, it was similar to that but with a fuzzy distortion in the tone on top of that. Both amps eventually went brain-dead in the preamp, but still worked plugging the bass into the effects-in (clean there, tho).
I think GK had a bad run of amps a few years ago in the RB series, since I hear about other guys having this problem literally all over the place here on TB. And 2 heads right in a row is what I'd call a high failure rate for sure.
Mine were both still under warranty, so GK fixed them for free. One of my heads had an IC replaced in the preamp, the other from what I could gather from the work order they just reran the solder on some of the joints on the circuit board. I don't think they had to replace components on that one.
Like I said, tho, after GK fixed them they've been fine. So I'm still a very satisfied GK owner. But my guess is yours is one of those from this run of bad amps. So I wouldn't waste any time on it - I'd call up GK directly and send it directly to the factory for fixing. They seem to know exactly what to do to fix it..
