Note/disclosure: Rabbit Hole FX pedals are completely hand-made in-house including circuit design and assembly, enclosure polish/printing, final assembly, testing and packaging. You might notice a little variation in the look including artwork and knob selection sometimes, but we can assure that the pedal you see in the photo is the one you'll receive if purchased from us. The sound and functionality of Rabbit Hole FX pedals are consistent throughout unless otherwise noted, as replicability is a high priority in our process. 

The Rabbit Hole FX team thanks you from both USA & Germany, and we invite you to contact us anytime with questions and/or feedback and to purchase Rabbit Hole FX pedals from any of our trusted dealers or from us directly at

Cheers ~
