Holy Superdistorter. Caroline Guitar Company introduced some nasty at NAMM with the debut of the Wave Cannon MKII. The pedal can do some very cool mild-to-medium crunch tones, but is also capable of really overwhelming your amp. Caroline put plenty of gain and volume on tap—inspired by infuriation in the past with great sounding classic distortion pedals that didn’t go far enough with clean amps, or were quieter than unity gain or the bypass signal. The rumble switch allows more low end when wanted, or tightens things up if you don’t need it. $199 street.
