I want to ask if someone can verify that the following happens on their Helix as it does on mine before I file a bug report. I searched for this before creating this topic, if it's a dupe I'm excusing myself beforehand. I use Firmware 2.21 .
I recommend using a DAW or method B to make sure there's no additional noises coming from pickups, cables etc.
Symptom: Both the SV Beast Nrm and Brt models exhibit a clicking noise after sound was processed if the "Sag" parameter is set to a value of 0.6 or greater.
Steps to reproduce:
1. Create a patch with just an SV Beast Amp in it. Set the "Sag" to a value equal or greater than 0.6, the other controls don't seem to have an influence. Set the input block to something quiet, e.g. USB.
Method A:
2. Connect the Helix to a DAW and use a routing with sound only going in and out via USB (Reamping).
3. Monitor the Helix' main output (Channels 1&2), e.g. by arming a track for recording.
4. Play anything for any amount of time, then stop playback.
Method B:
2. Set the "Hum" value to anything that produces an audible sound, then move it rapidly to 0.
For both methods, there should be a crackling noise following that sounds like static discharge going through a lowpass filter. For "Sag" settings of 0.5 or less, I could not reproduce the symptom. If someone can confirm this, I will file a bug report, otherwise I'll scratch my head. With a confused face.
