From Caroline Guitar Co:
WAVE CANNON “Zero” is both a throwback to one of our very first unreleased prototypes of a pedal and the culmination of decades of playing, repairing, modifying, and building these circuits. It can be wild, it can be mild, it can tear your head off, it can be warm like your granny’s gravy, or as nasty as you want to be.
Circuitwise, it shares a lineage with our original Wave Cannon v1 released in 2010, but functionally and sonically it takes things a lot further than our previous releases. We didn’t write any rules; we only wrote a manual. Where you take it is up to you. Making things dirty is just the start.
