    First, make sure it isn't something else, such as your speakers, hook-up cords, bass, or effects. It could even be a dirty potentiometer (volume control). Rule those out first. Then bring it back to the repair shop and explain the symptoms. It's possible something got damaged in the output stage. It's impossible to tell what it could be from your message. If it's not under warranty, then I recommend having the techs give you an estimated cost to repair it first. If that cost exceeds your limit, then you might just abandon it. That's up to you. IMO, it's probably something that could easily be repaired by a competent technician. Make sure your repair shop has skilled technicians.

  3. Make sure the the effects send/return jacks are clean. I have an MB-150E which suffered from the same symptoms - suddenly cutting out for no apparent reason. I struggled for days trying this and that and nothing worked. Thought it might be temperature related, but it turned out to be dirty contacts on the send/return jacks. GK boobed by using jacks that don't have the "wiping" action contacts (self-cleaning) but instead have the "point-contact" type, which work fine until they get crudded-up, they they fail, and have to be cleaned... aaarrrgghhh - took hours to find that out! There - now you have the benefit of my experience! ;>

  7. Well, neither do I, but the send/return normalise to straight-through, and if the contacts are bad...

    PS: You could try putting a patch-cable from the send to the return - that might by-pass the offending contacts - then you'd know for sure...
