FOXROX Wah Retrofit

Did you ever notice that your Wah Wah pedal doesn't cut it when plugged into some effects, such as the Dallas Arbiter Fuzz Face, or Fuzz Face clone? This is something that has annoyed guitarists since the late 60's. But now there's a remedy - You can get FULL RANGE out of your Wah Wah pedal with the Foxrox Wah Retrofit. If this sounds interesting to you - READ ON!

Foxrox Electronics is proud to offer the ideal remedy to this problem. The Foxrox Wah Retrofit is a self-contained FET buffer/amp circuit that gets installed into your Wah Wah pedal, giving it the ability to cut through any Fuzz Face or Fuzz Face clone. By essentially installing a "real" output section, the Wah Wah pedal becomes immune to the effects of loading, restoring range and depth to older, vintage Wah wah pedals without affecting their vintage value. Newer, high-end "boutique" wah pedals, such as Teese RMC pedals also benefit from this mod because they are based on the same, classic inductor-based circuit. Since it is a basic FET audio buffer/amplifier, this circuit can also be added to effects pedals that need more output, as well as effects that need more drive at the input. NOTE: A Teese RMC wah with the Foxrox Wah Retrofit, going into a Captain Coconut (1 or 2) is guaranteed to deliver the best wah/fuzz/vibe/octave sounds you've ever heard!


  • Connection wires: RED = +9 Volts, DC; BLACK = Ground; Orange = Input; PURPLE = Output
  • Volume: Trimmer offers continuous volume control with some available extra gain (around 3 dB). Some of the best Wah Wha pedals out there have an inherent boost that (without this mod) can't be attenuated without affecting the sound of the Wah. The Foxrox Wah Retrofit makes it possible to add or cut the level without affecting the Wah pedal's natural tone. The FWR can also be built to give up to 15 dB of gain, available upon request. However this is not recommended for wah wah pedals because of possible distortion during resonant peaks.
  • Update your favorite wah with the Foxrox Electronics Wah Retrofit. The Foxrox Wah Retrofit remedies reduced wah range. The Wah Retrofit will enhance your wah's vocal pronunciation when combined with fuzzes, allowing you to get the most out of your pedals. The Foxrox Wah Retrofit is easy to install and built to last!
