You “administrate” and “verbally chastise” selectively. I initially chimed in on another thread where someone else was experiencing the same issue, which, is an annoying high pitched humming sound. See below.

I guess I assumed my references to the “Hum Debugger” would have tipped you off to the problem within the context of the thread.

One of the biggest selling points by EHX on the 44 Magnum was “how clean it sounds”. It’s simply not true. I assumed that it was a ground loop issue at first because the “amp” by itself was RELATIVELY clean (with a little hiss, no biggy) at the “8 o’clock” position that I was using it at. The “gnat buzzing” sound only happened when I fed the stereo out side of my effects loop to the 44. So, then I tried all the aforementioned methods to eliminate what I thought to be ground loop.

Once the borrowed power conditioner failed. I once again went straight into the 44 and started dialing up the knob to where it “overdrives”. Low and Behold, the SAME high frequency hum revealed itself and led me to the conclusion that it was a problem inherent to the 44 itself (or it’s power supply) and NOT the product of ground loop.

I had seen this as a known issue on reviews, but it seemed to be mostly contained to Keyboard players.

Thanks for being so helpful instead of hostile, Admin. Oh wait…..
