Howdy folks. I recently picked up a Delta 1010 (not the LT version). It's been working out great, except for one little thing. It seems like the +4/-10 switches are causing the signal to cut in and out, but usually only with low level coming in. This is really only a problem on dynamic sources. Once a signal, like a distorted guitar, comes in strong and stays strong, it doesn't cut out. Wiggling the switches causes it to cut in and out too. And this is all regardless of whether it's set to +4 or -10.
Contact cleaner? New switches?
