I am trying to record using my Code 25 amp.
When I record, i get a strong scratchy, hissy noise that happens regularly for 5 seconds every 15 seconds.
I've swapped cables, guitars, computers, etc. and still get the hiss. I swapped amps with an older Vox modular amp and the recording is fine. So it almost certainly a problem with the Code 25. Of course I bought the Marshall amp to replace the Vox because I don't like the Vox's sound, so just using the Vox is not an option.
Any suggestions? What could cause the interference I described through the Code 25?
(BTW, I'm recording with very high quality USB/guitar cables, a JP Majesty guitar, and audacity.)
