Sustainiac squealing / not working properly
Hey, I bought a MB NE with Sustainiac a few weeks ago.
The guitar is perfect and it's so fun to play. No regrets.
The only thing that makes me a bit sad is that recently the Sustainiac started to act weird:
- When guitar volume knob is at max, the Sustainiac does not work at all.
No sustain, no matter what mode. The neck pickup works fine.
- When I lower the volume, the Sustainiac kinda works as it should.
However, in harmonic mode, I get a high pitched squeal from the amp even when I'm not playing anything. Mix and fundamental modes are fine, no squeal.
I already changed the battery and checked the voltage with a multimeter. It's fine.
I really hope that I can fix it without sending it to Manson for repair but I'm not really well educated when it comes to anything related to electric circuits.
Did any of you have the same / similar issue with your Manson guitar or Sustainiac?
If so, how did you fix it?
Edit:
I just traced it back to my Kemper Profiler: I've got a preset with a Kemper Fuzz.
When "True Imp." is enabled, the Sustainiac dies.
When I disable it, the Sustainiac works fine.
So I guess it's not the Sustainiac after all.
