The Green Carrot Comfortably Plum is a two-circuit pedal from Green Carrot Pedals that combines a Ram's Head-style Big Muff fuzz circuit with an independently switched circuit based on the Colorsound Power Boost boost1. Each side has its own bypass footswitch, so you can use the Muff alone, the boost alone, or stack the boost into the Muff the way David Gilmour did with the originals: MusicRadar notes that a trick Gilmour particularly enjoys is using the Power Boost to enhance the Muff's sustain and presence1.
Guitar World's Trevor Curwen describes it as "two classic, independently switched circuits in one pedal," and classifies it as a fuzz and drive/boost pedal2. MusicRadar describes the maker as Yorkshire's Green Carrot Pedals and lists the pedal's origin as USA1.
Two circuits in one pedal
The Comfortably Plum's appeal is that it puts two circuits with a shared history in one enclosure. The left side is a Ram's Head-style Big Muff, the mid-1970s Muff variant known for smooth sustain and string clarity. The right side is based on the Colorsound Power Boost, the 1970s British booster whose treble and bass controls let it push an amp or add grit on its own. Green Carrot's version augments the Power Boost circuit with a volume knob for adjusting the output level1.
Because the two footswitches are independent, the pedal covers three configurations:
- Muff side alone for Ram's Head-style fuzz
- Power Boost side alone, from a gentle clean boost through to fuzzy crunch with the drive control maxed out1
- Both together, with the boost enhancing the Muff's sustain and presence, the combination Gilmour is associated with1
On That Pedal Show, the hosts noted the Muff side carries a switch with a couple of level options, and found the pedal very sweet with a Strat, though they felt the low gain Ram's Head sound was not really achievable, with gain running from zero to 12 o'clock3.
The controls
Each channel has its own control set12:
| Channel | Controls |
|---|---|
| Muff (Ram's Head-style) | Volume, Sustain, Tone, midrange Shape switch, bypass footswitch |
| Power Boost | Treble, Bass, Drive, Volume, bypass footswitch |
The Shape toggle on the Muff side is the notable extra over a standard three-knob Muff. It lets you boost the midrange by 4dB or 10dB depending on where you set the tone, or alternatively scoop the mids for the classic Muff voicing1. Guitar World frames it as "a toggle switch supplementing the three knobs to add a midrange boost (4dB or 10dB) to the classic Muff scooped" sound2.
On the Power Boost side, the Drive control runs from a gentle clean boost, dialling in some hair as you go, right through to some fuzzy crunch when maxed out1. Guitar World found this channel "eminently responsive to picking dynamics and guitar volume"2, and MusicRadar's reviewers found it highly responsive to playing, noting that the treble knob can bring out a really up-front high end to make solos cut through1.
What reviewers said
Both print reviewers focused on how the Muff side delivers the Ram's Head character. MusicRadar found it delivers "the smooth sustain and abundance of clarity and string-articulation that we'd expect from that Muff"1, and Guitar World agreed that the Muff circuit "sounds typically Ram's Head-like with the smooth sustain and string clarity that it's noted for"2. Guitar World listed the extra Big Muff midrange options among its reasons to buy2.
MusicRadar's overall verdict:
"Gilmour fans will be all over this but the broad sweep of drive, distortion and fuzz tones is enough to pique anyone's interest"1
On That Pedal Show in November 2019, Mick and Daniel demoed the pedal and judged the combined sound to be something special, with Mick saying of the two circuits together3:
"we can keep listening to that all day because it's totally magic"3
They expected the pedal to sell extremely well3.

Questions
Is the Green Carrot Comfortably Plum true bypass?
Yes. Both MusicRadar and Guitar World list the Comfortably Plum as true bypass in their reviews, so with the pedal disengaged your signal passes through without buffering or coloration.
What does the Shape switch do on the Comfortably Plum?
The Shape toggle on the Muff side supplements the Volume, Sustain and Tone knobs. It either boosts the midrange by 4dB or 10dB depending on where the tone is set, or alternatively scoops the mids for the classic Big Muff sound. Guitar World calls the extra midrange options a reason to buy.
Does the Comfortably Plum come with a power supply?
No. It runs on a 9V DC adaptor, which is not supplied, and draws 30mA. You will need to provide your own power supply.
Can the Muff and Power Boost sides be used separately?
Yes. The two circuits are independently switched, each with its own bypass footswitch, so you can use the Ram's Head-style Muff on its own, the Power Boost side on its own, or run the boost into the Muff to push its sustain and presence.
How much current does the Comfortably Plum draw?
The Comfortably Plum draws 30mA at 9V DC, according to both MusicRadar and Guitar World. That is modest by modern standards and easy on most pedalboard power supplies.
