The Fatbee Overdrive "Greeny" is an overdrive pedal from Beetronics, and the first pedal in the company's Babee Series. Beetronics describes it as a fully original circuit, designed in collaboration with the pedal designer Howard Davis, built around a Jfet drive stage that "breaks up sweet and smooth like a tubee amp." The company positions it as a flexible low-gain to medium-gain drive: "The Fatbee can be used to warm up, sting or buzz any instrument."1
What it does to your sound
Beetronics' own description is the reference point here:
"A Jfet drive like no other, breaks up sweet and smooth like a tubee amp."
Jfet stages are often used to give a pedal an amp-like breakup character, and the maker's framing puts the Greeny in that territory rather than in hard clipping distortion. The company suggests three uses for it, which read as a drive pedal with usable range from light to fairly aggressive1:
- Warm up an instrument
- Add a sting
- Push it into a buzz
It sits in the overdrive family alongside other Beetronics drives such as the Fatbee and the Nectar Tone Sweetener, and more broadly with the circuits covered on the Overdrive Pedals page.
Size, power and practical details
The Greeny runs on a 9VDC power supply with a center-negative plug and draws 36mA, figures that come from Beetronics' own product page. A draw of 36mA is high enough that a player should plan for a dedicated supply output rather than sharing one with several pedals on a daisy chain.1
The Greeny draws 36mA at 9VDC. That is more than some individual daisy-chain outputs provide, so plan your supply accordingly, and remember no power supply comes with the pedal.1

Questions
Does the Beetronics Greeny come with a power supply?
No. Beetronics states on the product page that the Fatbee Overdrive "Greeny" does not include a power supply. It requires a 9VDC supply with a center-negative connector and draws 36mA, so a standard pedal supply works, but you will need to use one you already own or buy one separately.
Is the Beetronics Fatbee Greeny still available?
As of 25 October 2026, the Beetronics product page lists the Fatbee Overdrive "Greeny" as sold out. Beetronics has run other versions of the Fatbee circuit, and the company's Custom Series has carried additional Fatbee editions, so the design itself has appeared in more than one form.
How big is the Beetronics Fatbee Overdrive?
Beetronics gives two sets of figures on the product page and they do not match. One lists the dimensions as 4 1/2" x 2 1/4" x 2 1/4" with a pedal weight of 0.5 lbs (0.25 kilos); another lists 5.5" x 3.5" x 2.75" including knobs and switches, at 0.75 lbs (0.5 kilos). Either way it is a small pedal.
Is the Greeny based on a Tube Screamer?
No. Beetronics describes the Greeny as a fully original overdrive circuit, designed in collaboration with pedal designer Howard Davis, and built around a Jfet drive stage. It is not presented as a Tube Screamer clone or any other existing circuit.
What polarity does the Greeny need?
The Fatbee Overdrive "Greeny" requires a 9VDC power supply with a center-negative connector, the same polarity used by most modern pedals. It draws 36mA, which is more than some daisy-chain outputs deliver, so a dedicated supply output is the safer choice.
