This pedal is VERY capable of fun runaway oscillations, both by turning up the summation knob, or a controlled, high-pass filtered oscillation from the Havoc momentary foot switch. If you’ve ever struggled to make your delays come through prominently in the mix, or lost definition from your original signal, the attack and level controls can allow you to dial up everything from crisp, clean slapbacks to dirty, muted echoes and loud, powerful repeats. A beautiful, subtle modulation circuit of Jack DeVille also sweetens the repeats with just the right amount of movement.
