Coda Effects Dolmen Fuzz

The Coda Effects Dolmen Fuzz is an analog fuzz pedal built in France, designed around the circuit of the Russian-made Big Muff from the 1990s and aimed squarely at doom and stoner players. Coda Effects describes its sound as "a huge powerful sound, with a lot of bass and mids frequencies", with huge sustain and an available mid boost¹. The Russian Big Muff it draws on is the version Coda notes was used by "heavy" stoner and doom bands like Fu Manchu and Kyuss, and by rock bands like Dinosaur Jr and the Black Keys¹.

What it does to your sound

The Dolmen follows the Big Muff recipe: a sustain-heavy, scooped fuzz voice, but with the mids put back in the player's hands. The Medium knob exists, in Coda's words, "to cut through the mix whenever you want", addressing the classic complaint that a Big Muff disappears in a band setting¹. RockBoard's PedalPedia entry for RockBoard's PedalPedia lists the circuit type as analog², and Coda states the pedal has an "Analog signal path : your signal is never digitized and stays at its best!"¹.

Two switches shape the response:

• Clipping switch: changes the compression and dynamic of the fuzz, so you can shift between a more open, dynamic feel and a tighter, more compressed one¹
• Solstice switch: for heavy sounds and noise drones¹

The Solstice footswitch itself is a SPST type, a detail Coda mentions in its own wiring write-up on true bypass switching³.

Big Muff roots

Coda Effects is explicit about the lineage: the Dolmen is "Inspired by the Russian Big Muff", specifically the "bubble font" version made in Russia in the 1990s¹. That makes it a Big Muff-style design rather than a straight clone, since the mid knob and clipping switch are additions to the original circuit's layout. Players who want to build the underlying circuit themselves can use the maker's Big Muff PCB, a double-sided board Coda describes as allowing you to "make your own Big Muff", based on the EHX Big Muff and, in the maker's words, "a very nice build for beginners" because the circuit is simple and easy to mod⁴. Coda also documents its own Big Muff builds on its blog, including a Black Keys Big Muff with an added mid control⁴.

Power and practicalities

The pedal runs on a standard 9V DC supply, center negative, drawing less than 50 mA, which Coda chose "to make the Dolmen Fuzz highly compatible with pedalboard use"¹. It can also run on a battery, which Coda points out is "for Fuzz afficionados", a nod to the way a dying battery changes a fuzz's character¹.

The price listed on the maker's page was 177 EUR¹.
