Mimmo’s Mods

Feel free to browse through the readily available modifications below. All mods are sorted alphabetically by manufacturer name, then model. If you do not see your pedal below, please use the contact form to inquire about alternate effects modifications!

BOSS CH-1 Super Chorus Vibrato Mod (Analog Version) – $35

Mimmotronics has developed a circuit installation for switching on & off the dry signal in the BOSS CH-1, allowing you to toggle between Chorus mode and Vibrato mode! Mimmo also employs a mod popularized by Brian Wampler to increase the range of the Rate parameter from the stock amount.


BOSS TR-2 Tremolo Dual Rate Settings Mod – $35

Mimmotronics offers the option to add another rate preset to your BOSS TR-2. Switch quickly between slow and fast tremolo rates for quick changes within your compositions, or use it as an additional preset for less shoegaze time between songs.


EHX Holy Grail Nano Dual Reverb Settings Mod – $45

The Holy Grail is one of my favorite simple reverb units, in that it’s very much a set-it-and-forget-it pedal. In an effort to make the Holy Grail more versatile, Mimmotronics offers the Dual Settings Mod for the Nano version. This allows the player to switch from a subtle, moderate amount of reverb to a vibrant, fuller version of the same mode, all in real-time.


Vintage EHX Power Adapter Mod – $35

Mimmotronics will swap out the stock (+)-tip power adapter for a standard (-)-tip BOSS-style barrel connector, allowing you to simply daisy-chain vintage EHX pedals with other (-)-tip 9V pedals. If needed, an LED can also be installed showing whether the pedal is engaged or not.
