paddy mcbride Posted November 7, 2017 Share Posted November 7, 2017 So here's a strange one. My Ampeg svt6pro has started clipping and creating an intermittent popping sound. I checked through my whole pedal board to see if the issue was there and couldn't fine any problems. Even when all cables except the power lead are connected, the clipping light flashes intermittently. It turns out, this only happens whilst my drummer is drumming....I know this sounds odd. Does anyone have any ideas, do you think there's a lose connection which is possibly vibrating? Might be time for a service so does anyone know a good amp tech in the manchester area? Any thoughts??

BassBunny Posted November 7, 2017 Share Posted November 7, 2017 Dave Lunt in Stockport is the man for amp repairs particularly as your amp has a mess of tubes in it. He is a valve guru. It could be one of the pre-amp valves causing the problem. Quote Link to comment Share on other sites More sharing options...

Bill Fitzmaurice Posted November 7, 2017 Share Posted November 7, 2017 It could be a microphonic tube. Gently tap on them with a pencil to find out. Quote Link to comment Share on other sites More sharing options...

RandomBass Posted November 7, 2017 Share Posted November 7, 2017 Make sure you use an HB. 2B's are too soft. Quote Link to comment Share on other sites More sharing options...
