The Greer Amps Supa Cobra is a medium-gain overdrive pedal that Greer Amps introduced at Summer NAMM 20181. The maker describes it as a versatile, touch-sensitive overdrive with natural, amp-like breakup, in a small enclosure2. Where most overdrives give you one clipping character, the Supa Cobra has a three-position toggle that switches between FAT, LED and Open clipping, which changes the texture of the drive itself rather than just its amount21.
What it does to your sound
Greer positions the Supa Cobra as an overdrive that responds to how hard you pick, with breakup that behaves like a driven amp rather than a stompbox2. Delicious Audio, covering the pedal at its 2018 introduction, called it a flexible medium-gain overdrive built with top quality components1. Premier Guitar later described its range as running from chewy medium gain overdrive to crunchy grind3.
The pedal's flexibility comes mostly from two places: the Body control and the clipping switch. Body is not a simple bass cut. Greer says it expands low-end content while pushing gain, so turning it up fattens the sound and drives the circuit harder at the same time2. The clipping toggle then sets how the circuit distorts, which is where the Supa Cobra differs from single-voice overdrives.
The controls
The Supa Cobra keeps its panel simple: a gain knob, Treble and Body controls, and a three-position clipping toggle21.
| Control | What it does |
|---|---|
| Gain | Sets the amount of drive; Premier Guitar's reviewer ran it nearly full up3 |
| Body | Expands low-end content while pushing gain; low settings stay cleaner with less boom on low notes2 |
| Treble | Sets the high-end content1 |
| Clip switch (3-position) | Selects the clipping style and texture: FAT, LED or Open21 |
The Body control earned particular praise in the press. Premier Guitar's reviewer wrote3:
"The Supa Cobra's greatest feature may be the body control that dials in low-end presence without adding any murk."
That combination, more low end without a muddy character, is what a player usually wants from a control like this, and it is the Supa Cobra's distinguishing feature among Greer's overdrives3.
FAT, LED and Open clipping modes
The three-position toggle is the heart of the pedal. Each position changes what does the clipping, and therefore the feel and texture of the drive21.
- FAT mode: the circuit clips in a fat, chewy way, per Greer2.
- LED mode: clipping becomes stiffer, with more crunch, most noticeable at higher gain settings. Greer compares it to a famous British amp sound that starts with an M2.
- Open (center) position: the clipping diodes are out of the path and the natural drive of the opamp is on display2.
Premier Guitar's reviewer preferred that center position, noting that, according to Greer, it bypasses the other modes' clipping diodes and lets the op amp's natural drive come through. In that setting the reviewer found the pedal "loud and clear and compressed in just the right way to let sustained notes really sing out in a natural, power amp-y manner"3. The reviewer also liked the Body control around 60 percent with the gain knob turned nearly full up3.
For comparison with other clipping architectures, see the Boss SD-1 vs Ibanez TS9 comparison, which covers how different diode arrangements shape an overdrive's character.
Power and connections
The Supa Cobra runs on a standard 9-volt supply with a negative center pin, using a 2.1mm barrel connector, and draws 12mA2. Greer specifies 9 volt negative center pin only2.
The Supa Cobra takes a 9V DC supply with negative center polarity and a 2.1mm plug. It does not run on a battery or a positive-center supply, so check your power brick's polarity before plugging in.
Bypass is true bypass, so the pedal does not buffer your signal when switched off2. The enclosure measures 4.77" x 2.6" x 1.39", a compact footprint for a pedalboard2.
Where it came from and where it stands
Greer's Supa Cobra is an overdrive pedal in a compact enclosure measuring 4.77" x 2.6" x 1.39"2. It sits alongside the Lightspeed Organic Overdrive and the Southland Harmonic Overdrive in the maker's overdrive lineup2. The pedal offers three clipping modes, FAT, LED, and Open, which a reviewer described as making it "a rather flexible pedal"1.
The Supa Cobra is no longer a standard catalog item. As of Premier Guitar's 2025 review it is available from Greer by special request only, and the maker's page says pedals are built to order and ship within 1 to 2 weeks of order and payment23.
Greer Amps backs the pedal with a lifetime warranty covering manufacturing defects and component failure to the original owner; misuse and abuse are not covered2.

Questions
Is the Greer Supa Cobra true bypass?
Yes. Greer Amps lists the Supa Cobra as true bypass, so with the pedal off your signal passes through without active buffering. That suits players who run short pedal chains or who prefer to place their own buffer elsewhere on the board.
What does the Body knob do on the Supa Cobra?
Body sets the low-end content, and it also pushes gain. Set low, the pedal stays cleaner with less boom on low notes; turned up, both gain and low-end presence increase. Premier Guitar's reviewer found it dials in low-end presence without adding any murk.
Is the Greer Supa Cobra still made?
As of Premier Guitar's 2025 review, the Supa Cobra is only available from Greer by special request, and the maker's page describes pedals as built to order. It is not a standard stock item, so a player wanting one needs to contact Greer directly.
How long does a Greer Supa Cobra take to ship?
Greer Amps states that pedals are currently built to order and ship within 1 to 2 weeks of your order and payment. Because availability is by special request, it is worth confirming timing with the builder when ordering.
What warranty does Greer Amps give on the Supa Cobra?
Greer Amps' lifetime warranty covers manufacturing defects and component failure for the original owner. It does not cover misuse or abuse, so damage from rough handling or modification is outside the warranty.
