Chris Dow Posted May 3, 2020 Share Posted May 3, 2020 Hi, I haven't played live for about a year and subsequently my gear has not been used. I decided to power up my GK 400 RB amp and GK 2 X 12 Neo cab the other day and I noticed I was getting distortion on the end of a sustained note. The amp and cab sound perfect till you let the note ring you get this distorted effect on the tail end of the sustain, more noticeable on lower end. I used to have a back up amp and cab that I could try either of these to determine whether it was amp or speaker problem but I got rid of them when I finished live playing. Any ideas Amp or Cab problem. Cheers and thanks. PS I have sound file that you can hear problem. Quote Link to comment Share on other sites More sharing options...
Merton Posted May 3, 2020 Share Posted May 3, 2020 (edited) Does your bass have an active circuit with a battery? That’d be the first thing I’d check Edited May 3, 2020 by Merton Quote Link to comment Share on other sites More sharing options...
Chris Dow Posted May 3, 2020 Author Share Posted May 3, 2020 Hi Good thinking, Yes bass had an active circuit but I seem to remember I tried it with a passive bass also and same thing happened but will look more into that. Cheers Quote Link to comment Share on other sites More sharing options...
Dan Dare Posted May 3, 2020 Share Posted May 3, 2020 I had a similar issue recently and it turned out to be dirty contacts on the input jack. I sprayed the plug with switch cleaner, pushed it in and rotated/wiggled it a bit (oooer, missus) and it solved the problem. Quote Link to comment Share on other sites More sharing options...
