The Stomp Under Foot Ram's Head is a fuzz pedal built as a take on the Ram's Head version of the Electro-Harmonix Big Muff, the circuit that shaped fuzz tones through the mid-1970s. Where the original Ram's Head came in a large folded-metal enclosure, Stomp Under Foot's version is a small, MXR-sized unit in a purple solid metal casing, with modern wiring and power, which makes it easy to fit on a pedalboard12.
The current version is based on the rare 1974 V11 circuit, which the maker describes as having "become a favorite among fuzz enthusiasts"1. It carries the three controls every Big Muff user knows, Sustain, Volume and Tone, and is hand-built in the USA with NOS through-hole components, new-old-stock parts of the kind found in the original 1970s pedals21.
What it does to your sound
Stomp Under Foot says the V11 circuit "delivers a richer, fuller, woolier tone on the lower notes, while the highs offer a punchier, smoother lead tone with rich harmonics and long, singing sustain"1. That is the classic Big Muff character: heavy sustain, thick chords and a scooped midrange that leaves room for bass and treble.
Reviewers have backed that up against the vintage originals. Pedal of the Day's reviewer wrote in 201532:
"I thought it accurately captured the sounds of those old machines really well, and having the modern innards and smaller enclosure"3
The same review described "sustain for days and that thick, classic fuzz sound that fuzz enthusiasts crave," and noted the pedal fits easily onto any pedalboard, is light, and features modern wiring and power3. Premier Guitar's reviewer found the Ram's Head "yields a huge tone, full of analog warmth and open overtones," particularly through a simple low-gain amplifier2.
The controls: Sustain, Volume and Tone
The control panel is the familiar three-knob Big Muff layout. Premier Guitar described it as "three knobs that will be familiar to any old-school Muff user, Sustain, Volume, and Tone"2.
| Control | What it does |
|---|---|
| Sustain | Sets the amount of fuzz injected into your signal path3 |
| Volume | Output level, with plenty of level on tap3 |
| Tone | Shapes the EQ, with deep low-end and warm highs that don't pierce3 |
That is the whole interface. There is no mids control on this version, no switches and no presets: like the original Ram's Head, the pedal is voiced by the circuit itself, and the three knobs handle gain, level and tone. Players who want to push the mids around have options in the same lineup, covered below245.
Circuit, versions and editions
The Ram's Head name comes from Electro-Harmonix history. The Big Muff Pi Version 2, made in the USA around 1973, carried a ram's head motif on its graphics and is the version players call the Ram's Head. Kit Rae's Big Muff history notes the V2 was essentially the V1 circuit in a larger enclosure, and that Pink Floyd's Animals and The Wall album solo tones are examples of this pedal in use6.
Stomp Under Foot's founder, Matthew Pasquerella, has documented the many circuit variations inside the 1973 to 1974 Ram's Head era, and the company offers several of them as distinct pedals178:
- Ram's Head: the standard version, based on the rare 1974 V11 circuit1
- Ultra 47 Ram's Head: based on a rare 1973-1974 Ram's Head circuit, with an added mids control; the 47 symbol on the knob marks the classic mid-scooped setting, up from there adds mids and down gives a deeper scoop7
- Violet Menace Ram's Head: based on the Violet Ram's Head, one of the most popular circuits of the early 1970s, also with an added mids control whose Ram's Head symbol marks the original circuit's approximate setting9
The Ultra 47 and Violet Menace give players something the original never had: a way to fill in the scooped mids for more cut in a band mix, while still returning to the vintage voicing. Kit Rae, who has reviewed Stomp Under Foot's work at length, notes that the company's '73 Ram's Head began as a one-off replica he asked the builder to make of an original 1973 Ram's Head Big Muff, and became a regular offering in the Stomp Under Foot line in 2011; he describes its character as "dark, scooped mid tones, smooth grit, and a thick bottom end"87.
The Ram's Head line has changed over time. The 2015 and 2020 reviews describe earlier circuits, including the '73 version, while the current standard Ram's Head is built on the 1974 V11 circuit138.
How it compares with other Ram's Head pedals
The Ram's Head circuit has been revisited by several makers, and the differences are mostly about enclosure, components and controls:
| Pedal | Basis | Distinct points |
|---|---|---|
| Stomp Under Foot Ram's Head | 1974 V11 circuit1 | Small MXR-sized enclosure, NOS through-hole parts, true bypass12 |
| Electro-Harmonix Ram's Head Big Muff Pi | EHX reissue of the Ram's Head | Nano-sized enclosure, true bypass, 9V battery included1011 |
| Vick Audio 73 Ram's Head | 1973 Ram's Head | Three-knob Volume, Tone, Sustain design, true-bypass switching12 |
| Buffalo FX Ram's Head | Original Ram's Head | Sustain, level and tone controls mirroring the original13 |
The practical difference for a player is size and parts. The original V2 Ram's Head was a large enclosure; the Stomp Under Foot version puts the same style of circuit in a housing that fits a crowded board, with modern power wiring23.
Power, bypass and practical details
The Ram's Head runs on a 9V battery or a 2.1mm 9V adapter, the standard pedalboard connector, and nothing else is listed1. It is true bypass, so the circuit is out of the signal path when the pedal is off1. The build uses NOS through-hole components, and each unit is handmade in the USA1.

Questions
Is the Stomp Under Foot Ram's Head based on a Big Muff?
Yes. It is Stomp Under Foot's take on the Ram's Head version of the Electro-Harmonix Big Muff, specifically the rare 1974 V11 circuit, which the maker describes as a favorite among fuzz enthusiasts. Reviewers have compared it directly to the sound of the vintage Ram's Head machines.
Does the Stomp Under Foot Ram's Head take a battery?
Yes. It runs on a 9V battery or a 2.1mm 9V adapter, so it works with a standard pedalboard power supply as well as a battery. The maker lists no other power options.
Is the Ram's Head true bypass?
Yes. Stomp Under Foot lists the Ram's Head as true bypass, so with the pedal switched off your signal passes through without the circuit coloring it.
Where is the Stomp Under Foot Ram's Head made?
It is handmade in the USA by Stomp Under Foot, and built with NOS through-hole components, meaning new-old-stock parts of the type used in the original 1970s pedals.
