    Try cycling a 1/4" plug in and out of the send/return jacks. They may just need reseating.

    You could also slip a piece of paper between the contacts of the input jack. You'll have to open it up to do that, but I've seen it work on a similar problem with an Alembic preamplifier. Voila- silence! Until playing, of course... :D

    +1 to a good cleaning of all the jacks, switches and pots. Does the crackling seem to be related to turning any particular knobs?

    no its just when i play. my guitarist thinks it might be the cabinet.

    Try to isolate which piece of gear is causing the problem,, i.e., the instrument, the lead, the amp. the speaker cable, the speaker, etc. Once you've narrowed it down to what item has the problem, fixing it becomes much easier.

    +1 on isolating the issue. I have a 1001rb-ii and had to send it in a few months ago because it had some faint crackling and poping sounds. GK said it had a bad transistor when I got it back. The amp has been perfect ever since.

    does GK cover that?
  10. did you clean all the jacks yet - expressly the effect send/return jacks with De-Oxit cleaner yet?

    They have a 1 year warranty that does but I think you have to pay shipping. I had a coverage plan with the company I bought it from so everything was covered. It is my understanding that even if it is no longer under warranty they will repair it, they just charge you.
  12. Does it happen to every note you play, or just some notes? Does it matter how loud the amp is or how hard you play?

    I have a problem with my old MB150E where certain notes will loudly distort. Sounds similar to the "messing-with-input-jack" roar. But only on some notes. And does not seem to happen when playing lightly/quietly.

    I'm not an expert, but if you have having similar symptoms I'd vote for your problem not send/return/jack related. Speaker or electronics might be the source.

    yeah its on certain notes, the harder i hit my strings the more prominent it is. same if i turn my mids up, the noise gets worse
