[QUOTE="mrtatemyballs, post: 133519, member: 3250"] UPDATE: The volume pot was not the culprit. I ordered a foglifter board from Rob since I wanted one anyway. I had to call him on the install because my original board had the pinout in a different order. i got it installed and it really made a nice difference in the overall clarity of the amp and the useable low end. Unfortunately, it did not fix the problem.....so it's safe to say the volume pot is not the issue. Here is what I have found: When I play the amp WITHOUT anything plugged in to the "boost" jack, the amp acts up by jumping back and forth from whatever volume I have set to 10 sporadically. When I plug a cable into that jack, the problem magically goes away. It doesn't even matter if I have the boost engaged or not, just putting a cable in the jack fixes the problem. I have had several 3 hour plus rehearsals lately, and as long as I keep something plugged in the boost jack....no problems. As soon as I remove it....problems. Pretty sure my boost jack either has a bad solder joint, or is just failing mechanically and needs to be replaced. Any thoughts anyone? Also having a problem with my effects loop, but I will start a new thread to keep this one localized to this problem only. [/QUOTE]
