The Greuter Audio Moonlight is an analog low-gain fuzz pedal made in Switzerland. RockBoard's PedalPedia describes it as "the Greuter version of the legendary Fuzz Face," the vintage fuzz circuit known for cleaning up when you back off the guitar volume, and says the Moonlight was designed "to adapt better without loosing the vintage character and feel"1. Guitar.com's review called it "an elegant low-gain fuzz"2.
Controls and how it responds
The Moonlight carries four knobs plus a single on/off footswitch3. The bias control is the addition over a stock Fuzz Face, which traditionally offers just volume and fuzz, and it lets you set how the transistors behave at the edge of breakup.
| Control | What it does |
|---|---|
| Input | Sets the signal going into the fuzz stage3 |
| Fuzz | Sets the amount of fuzz3 |
| Output | Sets the pedal's output level3 |
| Bias | Sets how the transistors behave at the edge of breakup3 |
The volume-knob response is central to how the pedal is meant to be used. RockBoard's PedalPedia says it "responds to guitar volume pot for clean, overdrive and fuzz sounds," and suggests: "Set a fuzz sound you like and roll down the volume on your guitar and get wonderful clean sounds, dirty but dynamic over[drive]"1. That makes it a pedal you can leave on and play the whole range from your guitar, rather than stomp on for one sound.
What reviewers said
Guitar.com's review describes the low-gain response in detail: "we encounter a deliciously hairy overdrive with just a hint of sawtooth to keep it honest. It's a pokey sound with bite at the front end of the note blossoming into a sustained rasp"3. The same review confirms the pedal is a germanium fuzz, true-bypass, and made in Switzerland3.
"an elegant low-gain fuzz"
The £220 price comes from Guitar.com's February 2021 review3.
Power and placement on a board
The Moonlight runs on 9V DC, center negative, and draws 3.7mA1, a small draw by pedal standards that any standard isolated supply handles easily. Its footprint of 120 x 56 x 165mm3 is larger than a compact pedal, so it takes a little more board space than a mini enclosure.
If you are comparing it with other fuzz pedals, the Fuzz Face lineage is the key reference: like that circuit, it is a volume-knob-responsive fuzz, but with added bias and output controls and a low-gain character that Guitar.com heard as sitting closer to a dynamic overdrive than a full-on fuzz at the low end of its range13.

Questions
Is the Greuter Audio Moonlight a Fuzz Face clone?
Greuter Audio describes the Moonlight as its own version of the Fuzz Face, the classic two-knob fuzz design. Rather than a straight copy, the maker says it was designed to adapt better while keeping the vintage character and feel of the original circuit. It adds more controls than a stock Fuzz Face, including bias and output knobs alongside the input and fuzz controls.
Does the Moonlight clean up with the guitar volume knob?
Yes. Greuter Audio says the pedal responds to the guitar volume pot, so you can set a fuzz sound you like and roll the volume down for clean, overdrive and fuzz sounds from the same setting. Guitar.com's review found a low-gain response described as a deliciously hairy overdrive with just a hint of sawtooth.
What power supply does the Greuter Audio Moonlight need?
The Moonlight runs on 9V DC with center negative polarity and draws 3.7mA, according to the maker's specifications. That low current draw is easy on a pedalboard power supply, though the maker's page does not list a battery option, so a standard center-negative supply is the way to power it.
Is the Greuter Audio Moonlight true bypass?
Yes. Guitar.com's review lists the Moonlight as true-bypass, meaning the signal passes through the pedal untouched when it is switched off.
Where is the Greuter Audio Moonlight made?
The Moonlight is made in Switzerland, as Guitar.com's review notes in its verdict on the pedal. Greuter Audio is the Swiss maker behind it.
