clauster Posted March 13, 2011 Share Posted March 13, 2011 I'd start by giving the pots a good clean. Quote Link to comment Share on other sites More sharing options...

Big_Stu Posted March 13, 2011 Share Posted March 13, 2011 Was it stored somewhere where it couldn't be knocked about? My guess is pre-amp valve on the way out - or knocked loose if that's possible? Though I am no amp expert, I've had it happen with my valve head. Quote Link to comment Share on other sites More sharing options...
