Product information "Z.VEX Tremolo Probe Handpaint"
This is a hopped-up volume pedal with an SHO at its heart, providing boost, and a copper probe plate like a Fuzz Probe. As your foot gets closer, the volume goes up, but unlike a conventional volume pedal, there are no moving parts so you can create instant swells and tremolo effects by tapping your foot on the pedal in time with the band.
Control options: Volume
Pedal Dimensions (LxWxH): 7.50" x 4.70" x 2.40"
Limited, hand-painted version (colors and motif may vary)
