The Stomp Under Foot MCG73 is a fuzz pedal handmade in the U.S.A. that clones a vintage 1973 Ram's Head Big Muff, one of the most sought-after eras of the fuzz pedal family. Builder Matthew Pasquerella based it on one of the 1973 Big Muff pedals in his own collection, and Delicious Audio's Paolo De Gregorio describes this as a rare version of the circuit, set apart by some interesting capacitor choices1.
What it does
The MCG73 recreates a specific 1973 Ram's Head Big Muff from the builder's collection. In Pasquerella's words, "the MCG 73 is based on one of my favorite 1973 Big Muff™ pedals in my collection"1.
"This is a rare version due to some interesting capacitor choices and gives the pedal a full-bodied tone with a big low-end but is still balanced and warm."
For a player, that means a Big Muff-style fuzz with a pronounced low end that stays balanced and warm rather than thin. The capacitor choices are what distinguish this version from other 1973 Ram's Head circuits1.
Power and practical details
The pedal runs on a 9V battery or a 2.1mm 9V adapter only, and draws 4mA1. That is a light draw, so a battery lasts well and the pedal is an easy fit on a standard pedalboard supply.
- Bypass: True-Bypass1
- Power: 9V battery or 2.1mm 9V adapter only1
- Current draw: 4mA1
- Build: Handmade in the U.S.A.1
Where it sits in the range
Stomp Under Foot builds a number of pedals from vintage Big Muff circuits, each named for the version it recreates. Others in the range include the Ram's Head, the Green Russian, the Civil War, the Op-Amp Fuzz and the Ultra 47 Ram's Head. The MCG73 is the builder's take on one particular 1973 Ram's Head example, chosen for its rare capacitor values1.

Questions
What is the Stomp Under Foot MCG73 based on?
The MCG73 is a clone of a vintage 1973 Ram's Head Big Muff, built from one of the 1973 Big Muff pedals in builder Matthew Pasquerella's own collection. Delicious Audio describes it as a rare version of that circuit, set apart by some interesting capacitor choices that shape its tone.
How is the MCG73 powered?
The MCG73 runs on a 9V battery or a 2.1mm 9V adapter only, and draws 4mA. That light current draw means it is easy on a battery and should sit comfortably on most pedalboard power supplies.
What does the MCG73 sound like?
According to Delicious Audio, the capacitor choices in this version give the pedal a full-bodied tone with a big low-end that stays balanced and warm, rather than thin or harsh.
