The Tremolo Probe is a cross between a theremin volume control and a Super Hard-On. Tap on the antenna at any speed and your sound will be a smooth tremolo in time with the band. Rare handpainted Z.Vex blast from the past!
A theremin-style antenna controlling a wah, getting brighter as your foot approaches. It has one extra feature, however. There's a Super Hard-On boost circuit in front of the wah, with a knob to set the exact level of boost for driving your wah sound.
