Crazy Tube Circuits Killer V Vibrato Pedal

True pitch-shifting amp vibrato with built-in overdrive.

The Killer V by Crazy Tube Circuits is a fully analog vibrato and amp-style overdrive pedal, inspired by the unique pitch-shifting vibrato circuits found in classic California-built amplifiers from the 1950s and 60s. Using JFET technology and an internal voltage multiplier, Killer V delivers tube-like warmth, dynamic response, and authentic modulation.
