The Acorn Amplifiers Huge Vagina Muff Fuzz is a four-stage transistor fuzz with selectable diode clipping. The maker describes it as "a four stage transistor fuzz featuring a series of selectable diode clipping options," and it is the same circuit as the company's TMA-1 Fuzz, offered here in two different artwork designs1.
Clipping options and how the circuit works
The clipping scheme is the heart of the pedal. Three clipping choices are switchable in two separate stages of the fuzz circuit1:
- Germanium-mimicking diodes, for a softer, vintage-flavored clip
- Silicon diodes, for a harder clip
- Off, which bypasses the clipping diodes altogether
Because each of the two switchable stages can be set independently, you can pair germanium-style clipping in one stage with silicon in the other, run one stage with the diodes out of the circuit, or combine them in other ways1.
The same arrangement appears on the TMA-1, where the clipping options are described as Germanium diode, Silicon diode, or diodes bypassed (Off) on the second and third stages of the circuit43. Writing about the TMA-1, Delicious Audio's Paolo De Gregorio noted the pedal is "a four stage transistor fuzz featuring a series of selectable diode clipping options"3, and gearnews.com's Jef described the choice between "classic germanium and silicon diodes" as making "for a nice flexible fuzz c..."2.
The two designs
Acorn offers the Huge Vagina Muff Fuzz in two versions1:
| Traditional Design | 'Flower' Design | |
|---|---|---|
| Circuit | Four-stage transistor fuzz, same as the TMA-11 | Four-stage transistor fuzz, same as the TMA-11 |
| Clipping switches | Located by the jacks on the top side of the pedal1 | On the face of the pedal1 |
| Availability | Preorder, batch two1 | Preorder, batch two1 |
The circuit is identical in both; the difference is cosmetic, with one practical consequence for layout. On the Traditional Design, the clipping switches sit at the pedal's edge by the jacks rather than on the face, which matters if you plan to switch clipping options mid-song with your foot1.
The pedal is sold by preorder. Batch one has sold out, and batch two is open now, shipping on November 19th, 2026; batch one shipped on October 30th, 20261.
Power and where it sits in Acorn's range
The pedal runs on standard 9VDC center negative pedal power and consumes less than 60mA of current1. It sits alongside Acorn's other fuzzes, including the TMA-1, which shares its circuit1, the F#%k Face and the Epstein Didn't Kill Himself Fuzz. For more on the effect type itself, see Fuzz Pedals.
Questions
What power supply does the Huge Vagina Muff Fuzz need?
Acorn Amplifiers specifies a standard 9VDC center negative pedal power supply, and the pedal consumes less than 60mA of current. That is within reach of most standard pedalboard power supplies, though as with any fuzz it is worth using an isolated output rather than a daisy chain to keep the circuit quiet.
What clipping options does it have?
The Huge Vagina Muff Fuzz offers Germanium-mimicking diodes, silicon diodes, and a bypass of the clipping diodes altogether. These options are switchable in two separate stages of the fuzz circuit, so the two stages can be set differently and combined for a range of fuzz voices.
What is the difference between the Traditional and Flower designs?
Acorn Amplifiers offers the pedal in two versions, a Traditional Design and a 'Flower' Design. The circuit is the same in both. The practical difference is where the clipping switches sit: on the Traditional Design they are located by the jacks on the top side of the pedal.
Where is the clipping switch on the Traditional design?
On the 'traditional design' version, the clipping switches are located by the jacks on the top side of the pedal, according to Acorn Amplifiers' product page.
