Shechtl87 Posted March 24, 2022 Share Posted March 24, 2022 I got a used DT25 a few weeks back for a great deal and I'm noticing lots of hum on both clean and overdriven models. Touching different spots on my guitar doesn't affect the noise, but touching the switches on the amp makes it reduce. New tubes are coming if that is the issue, but I'm wondering if anyone had grounding issues that were caused by other factors Quote Link to comment Share on other sites More sharing options...
psarkissian Posted March 24, 2022 Share Posted March 24, 2022 1- Make certain they are the specified tubes. 2- Have an authorized Line 6 service center install, bias the tubes and test. 3- If you are touching a switch on the amp and noise reduces,... then you have a ground loop somewhere.

Shechtl87 Posted March 25, 2022 Author Share Posted March 25, 2022 Would repairing the cause of a ground loop be a long, expensive repair? I'm still within my return window if I happened to buy a busted piece of equipment. Quote Link to comment Share on other sites More sharing options...
Shechtl87 Posted March 26, 2022 Author Share Posted March 26, 2022 The back panel has this massive crease through it; it was packed very poorly by the Guitar Center and definitely tipped back multiple times in shipping with the power cord in place. Could this damage the internals enough to cause this ground loop? Quote Link to comment Share on other sites More sharing options...
