Hi everyone - I just received my Witch a couple of days ago, and have been trying it out. One thing I noticed is that when overdrive is the selected FX on one of the stock patches (SubTract by default, for example), there is periodic noise - not distortion - that lasts for 10 seconds or so. It sounds like sizzling. After 10 seconds the sizzling sound goes away, and then it comes back for another 10 seconds, etc. This even occurs when the level of the effect is turned all the way down using Knob E.
When I change the FX by setting CC89 to something other than overdrive (Delay in 32-63, or Chorus in 96-127, for example), the periodic sizzling goes away. Is there something that I can do to avoid this periodic noise when using overdrive?
Thanks in advance!
