Mattoverse Electronics - AirTrash
“The AirTrash is a pedal for guitar or bass that sounds like absolute garbage. I was breadboarding an idea and happened upon some absolutely sickening sounds, like really bad, but couldn’t stop playing it.  I spent a lot of time trying to refine and improve it, make it less noisy, more controllable etc.. but these changes always ended up sucking the fun right out of it so decided let it be the simple disgusting beast that it is.This pedal is not for everybody, not for most folks, completely impractical in any traditional sense.  After I let one of my bandmates check it out he said - “this is the last thing I would want to step on during a show”... but 15 minutes later he was still playing with it, making disgustingly awful sounds.  Your mileage may vary.It “works good” with guitar or bass, didn’t do much for me at all on synths or drum machines.  It’s very sensitive to the attack you play with and sounds best with the volume knob turned all the way up on your guitar or bass.The blue knob controls the output level.  I could not come up with words to properly describe what the red and yellow knobs do so I created those little icons in an attempt to illustrate what words could not describe.The prototype circuit did not end up getting changed at all so the three prototype demos below will work as accurate sound examples. I will build another batch as soon as possible...”
