The Gray Stache with Clean Blend Mod is a version of Fuzzrocious's Gray Stache fuzz pedal with a clean blend added, so you can mix your untouched signal back in alongside the fuzz. That matters most on bass, where a fuzz on its own can thin out the low end, but it also gives guitar players a way to keep definition under heavy fuzz.
The Gray Stache itself is a fuzz for both guitar and bass, modeled on the so-called Civil War-era Big Muff, with a mids control on top of the usual controls1. RockBoard's PedalPedia describes the result as "creating one versatile guitar AND bass-friendly monster!"2
What it does
The Gray Stache's defining feature is its mid-shaping tone stack. RockBoard's PedalPedia says it can scoop the mids for a heavy, deep sound, flatten them for an even-keeled sound, or boost them for a more modern sound that punches through the mix2. MusicRadar's reviewer, Alex Lynham, describes the three-way control as one that "alternately scoops them further, flattens them, or boosts them, for a more in-your-face, distortion-like tone"1.
Fuzzrocious offers a similar mod on other pedals in the range, such as the Demon with Clean Blend Mod.
Controls
| Control | What it does |
|---|---|
| Mids three-way | Scoops mids further, flattens them, or boosts them for a more in-your-face, distortion-like tone1 |
| Clean blend | Mixes your untouched signal in with the fuzz, preserving low end and definition |
How it compares
The standard Gray Stache carries the same circuit without the blend. Fuzzrocious has also built the Gray Stache into other variants, including the Gray Stache with Octave Jawn Mod and the Gray Stache/Heliotropic double fuzz, which pairs it with the Heliotropic circuit in one enclosure. Delicious Audio describes the Gray Stache side of that pedal as mids-forward, going "from light crumbly breakup to heavy, aggressive fuzz"4.
What reviewers said
Pedal of the Day's 2014 review of the Gray Stache found the control set rewarding: "they are all useful, and the more knobs you have, the more detailed you can get with your tone," adding that if you can't find a sound you like, "you're doing it wrong"3. MusicRadar's review was positive on versatility but flagged the price, listing "Pricey." among its cons1.

Questions
What does the Grey Stache's mids control do?
The Grey Stache's tone stack has a three-way setting that scoops the mids for a heavy, deep sound, flattens them for an even-keeled sound, or boosts them for a more modern sound that punches through the mix. MusicRadar describes the boosted setting as a more in-your-face, distortion-like tone.
Can the Grey Stache be used on bass?
Yes. The Grey Stache was intended for use on both bass and guitar, and Fuzzrocious describes it as a versatile guitar and bass-friendly fuzz. The clean blend mod is especially useful on bass, where keeping some untouched low end under the fuzz helps preserve the instrument's foundation.
