The Wave Cannon ZERO is the final form of the pedal that launched Caroline Guitar Company, a throwback to one of the first prototypes they ever made.
It's the result of decades of playing, studying, repairing, modifying, and then releasing multiple versions and flavors of op-amp “drivestortions”
On the drive side, if you just leave the voltage all the way up, ignore the havoc control, and just use the gain, shape, tone, and volume controls, you’ll have a wide range of beautiful, crunchy, and rich overdrive & distortion sounds that stack well with other pedals.
From Caroline, " Our updated Havoc control incorporates the positive feedback & oscillating mayhem you’ve come to expect from these pedals in ways we’ve never done before. While you can still run this pedal first in the chain for maximum interaction with your guitar, our new circuitry now makes this feature available later in your setup. Special switching by our longtime collaborator John Snyder at EAE allows the Havoc stomp to be momentary or latching, so you don’t have to hold it down while it’s going wild. And the combination of Havoc and our voltage starve control creates all kinds of new trouble, from just “extra dirty” to broken, weird, gated artifacts and envelope triggered collapses."
