Does anyone else hear (in their Helix) the artifacts that are on the audio posted in this thread? https://www.thegearpage.net/board/index.php?threads/helix-tell-me-what-im-hearing-here.1826645/ There are many topics on this but all the threads seem to get sidetracked in other discussions. I have the latest firmware and I definitely hear it on multiple amp cabs in my Helix. I've changed guitars, patches, all the components I can think of as variables and I believe it is related to the Amp cab in the Helix. I haven't found how to eliminate it but here's what I find minimizes it: The main thing that seems to influence it is the volume knob on your guitar. As you get towards the max guitar volume, it definitely shows up more. Reducing the volume will eventually make the sound disappear (before the whole sound is gone). Different cab models display different degrees of this. the Tweed Blues Brt amp seems to be the "cleanest". Raising the Bias setting minimizes, but doesn't eliminate the sound. The way i compared the cabs by setting my guitar volume about 7 or 8, signal directly into the cab. Then I would just change which cab was activated or not. The conclusion I have is that this sound is actually the "driven" portion of the amp, as you increase the input into the amp, this shows up. If that's the case, then it would really not be a "problem" in that it is just the digital simulation of the amp being driven. So it seems most noticeable as the amp is just starting to be driven harder. Once you get past a certain level, it is still there, just not as noticeable. Can anyone else weigh in? If you've been able to eliminate this, I'd love to know how.
