Hi guys,

Recently Im having this strange problem with this unit.
When I turn the knobs to select an effect, some just don't work.
They keep having the same sound as the effect before the one I want to select.

Some distortions dont work and some modulation dont work.
I already tried setting in to factory default etc.

Please help
They apparently aren't even build like tanks anymore.

you better check under the sea,
because that's where you'll find me..."
Yeah seriously, so a tank can survive bullets and minor explosives but apparently my AC-3 couldn't survive a small fall and now one of the knobs are bent.

I had one of these that I started having issues with. I took it into my friend who's an electronics tech, and he opened it up for me. Essentially, it's one big processor under the hood. It either works, or it doesn't. You can't do much to troubleshoot it.
