Hello, All: I have a CODE 50, about 18 months old. I usually play a "clean" preset, like JTM45, and when I take a break from playing and come back, the preset sounds like it has had distortion induced and/or gain set higher. This can happen in just a few minutes, or when I leave the amp turned on overnight. To rememdy, I turn the preset selector know one click right or left, and it clears it up. I've heard of one other person who has this problem, too. Anyone else out there experience this? If so, do you now of any "permanent" remedies? TIA!
When the sound changes, is the same preset selected, or is it changing by itself? If it's changing to another preset on it's own there may be a problem with the rotary encoder for the preset selectiion being worn. Also try disconecting the bluetooth app (if you use it), it has some bugs in it that can randomly change patches or settings within the patch.
