Zero FX | Clean Boost

Regular price $159.00

Adding a bit of simplicity without compromise to the high-quality standard to Rabbit Hole FX's lineup of very complicated pedals, the Zero FX is a transparent single-knob boost/cut pedal with:

  • Unity at ~ 8:45, so ~ 75% of your twist is boost and ~ 25% cut.
  • Range of ~ 4.7x boost at max and ~ 0.4x at min.
  • 3dB cutoff freq: the point at which output falls to .707 of the input, is 26Hz => Highly functional across a wide range of input frequencies but specifically great for bassists in the Rabbit Hole: ie. low-end is our friend.

Features Include:

  • Top-mounted input/output/power jack.
  • Industry standard 2.1mm 9VDC center negative power input jack and negative ground operation (no battery)
  • Small 125B sized pedalboard friendly enclosure.
  • Carling soft-switching relay-based True Bypass footswitch and all analog circuitry.
  • White LED indicator with internal trim pot to adjust brightness.
  • Enclosures are both machine and hand-polished to a mirror finish.
  • Durable and high-resolution UV Printed labeling and art.
  • Satin multi-purpose swag bag.
  • High quality parts used throughout for superior and consistent performance.
  • CE including ROHS compliance per European safety standards.
  • Forever Warranty.

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 ~
