***Modifications do not include the pedal itself. These prices are for the service to modify your pedal. If you would like to purchase a pedal that is sent to you already modded, please send us a message!

HiFi Mod: Upgrades stock value components for reduced noise and clearer tone.

Fullness Mod: Adds a toggle switch to bring more fullness to the tone.

MIJ Mods: If your pedal was made in Japan (MIJ,) it likely required a 12v aka ACU power supply to operate at proper efficiency. Some MIJ pedals might still work on 9v, but don't sound as good as they're supposed to.

  1. ACA 2 PSA: Converts the 12v ACA requirement to a standard 9v PSA requirement.
