I tried both Single and humbuckers. I am running a chord fron the output of the rocktron to the 2x12. That has a very tiny hum. Its when I plug any guitar in. I will do the trial and error thing over the weekend. Any suggestions?
Do you have anything else plugged in to a different outlet in your signal path? Try plugging everything into the same outlet. I'm assuming your power is grounded. Checking the ground is another thing you might want to do. If you don't have a volt meter you can go to the hardware or computer store and get a power strip with a ground check light.
