"The Anxious Echo was originally released as a preorder package piece for Coliseum's "Anxiety's Kiss". We combined the vintage octave fuzz of the toke machine (with led clipping on) with the spacey delay from the Unholy Grail with each effect having it's own true bypass footswitch so you can turn on one, the other, or both at the same time!" -Abominable Electronics

This pedal is in great shape aside from a few minor scratches and some velcro residue. If you're looking for a quirky fuzz/delay combo. Rocks.

Fuzz - volume of fuzz side
Bang - gain for fuzz side
Space - time between repeats on delay side
Infinite - feedback control on delay side
