Does anyone have any experience with the Ebtech Hum Eliminator (or any other brand, for that matter)? I'm going to use one to resolve a ground loop issue in a two-amp configuration.
That's correct. There are two versions: one with eight I/Os and one with two I/Os. I went for the latter. Got it for $36 incl. shipping, and they retail for $59, so I think I got a pretty good deal. The only issue is that it's used and the guy is seliing it as-is, so I may be taking a chance. For thirty-six bucks, I'll roll the dice.
