The MXR Super Badass Dynamic O.D. is a compact overdrive pedal from MXR, built around MOSFET clipping. MXR describes its overdrive as "a smooth purr that can be pulled back for a nice, clean boost or cranked into full gear for vintage high-gain grind"1. It is a basic three-knob design, Output, Tone and Gain, with a Boost/Cut toggle that shapes the midrange, and it was announced in September 2022 as the latest addition to MXR's Super Badass family23.
The pedal is widely compared to the Fulltone OCD. Both are MOSFET overdrives with a similar control layout, and Premier Guitar reviewed it as "MXR's excellent OCD-inspired stomp"4. Gearnews reported at launch that it "has a similar circuit to the Fulltone OCD pedal"5.
A MOSFET overdrive from clean boost to vintage grind
The circuit uses MOSFET clipping diodes driven by a Texas Instruments TL082 op-amp, "like that which powered many OCD units," according to Premier Guitar's reviewer, who also found a clean, economical layout on a through-hole circuit board4. Gearnews described it as a hard-clipping MOSFET, op-amp-driven approach, "a tried and tested method for creating overdrive tones"5.
What that means for a player: the drive character is touch-sensitive and preserves your existing tonal dynamics, in the words of Delicious Audio's presentation of the pedal8. MXR suggests it "sounds simply sublime when used to rev up a tube amp that's just about to cross the line"2. Premier Guitar's reviewer found that as a clean boost, "the MXR's output is full of body and adds little in the way of extraneous color to a fundamental guitar tone," calling it nearly as transparent as a Klon or a good klone4.
The controls and the Boost/Cut switch
The control set is straightforward, with one twist in the middle of the enclosure9.
| Control | What it does |
|---|---|
| Output Volume | Sets the output level6 |
| Tone | Shapes treble; wide range, useful with guitar volume attenuation4 |
| Gain | Adjusts overdrive intensity1 |
| Boost/Cut switch | Sets output mode: Boost raises output level and emphasizes midrange; Cut lowers output level1 |
| Footswitch | Toggles the effect on and off, with a red LED indicating on1 |
The Boost/Cut toggle is the feature that separates it from simpler three-knob overdrives. Premier Guitar's reviewer called "the primary difference between the MXR, or any other OCD homage, and simpler overdrives" its "midrange boost toggle"4. Guitar.com's Richard Purvis called it "the smart bonus feature here... a toggle switch in the centre for boosting or cutting the edginess of the midrange"9. Guitar World's Trevor Curwen found the pedal "tonally most neutral and transparent in the Cut position with the Tone knob set close to midway"6.
Power and connections
Setup is standard: an instrument cable from your guitar into the INSTRUMENT jack, and another from the AMPLIFIER jack into your amp's input1. Input impedance is greater than 450 kΩ and output impedance is less than 25 kΩ1.
Power comes from one 9-volt battery, accessible through a battery door on the bottom plate, or from a 9-volt AC adapter such as the Dunlop ECB003/ECB003EU, or an MXR Brick Series power supply2. At 6 mA of current draw1, it is light on a pedalboard power supply.
The third Super Badass pedal
The Super Badass Dynamic O.D. is the fifth MXR pedal with "Badass" in its name and the third of the Super Badass pedals, alongside the Super Badass Distortion and the Super Badass Variac Fuzz6. It was surprise-announced on MXR's YouTube channel in September 2022, before appearing on the brand's website3, and Delicious Audio reported it as a Guitar Center exclusive at launch8. Guitar World lists its origin as the USA6, and Guitar.com describes it as assembled in the USA9.
What reviewers said
Reviews were positive across the board.
- Guitar World (Trevor Curwen, 2026): "an excellent compact overdrive pedal with great dynamic sensitivity and a flexibility that will play a crucial role in front of both clean or driven amps"6
- Premier Guitar (2023): the pedal "walked the borders between clarity, body, and aggression with an unusual grace," and at $129 it "looks like a pretty great deal" as "a very capable OCD alternative"4
- Guitar.com (Richard Purvis, 2022): praised the midrange toggle, while calling the enclosure design "terminally frumpy" in its red-on-gray finish9
Premier Guitar's reviewer also noted how it responds to different guitars: single-coils "shine in its company," with a Telecaster bridge pickup sounding "more robust and meatier yet still lean and articulate," while humbuckers "coax a more rockist accent" with smooth high end that keeps thick tones clear of low-midrange mud. The reviewer found it "an especially dreamy match for a black- or silver-panel Fender amplifier," and thought its versatile control set would suit British amp voices too4.
On That Pedal Show in August 2026, Dan and Mick demoed the pedal alongside other new releases and were taken with it, with one remarking "that is genuinely amazing," and giving what they called a big up for the competition stripe graphics10.

Questions
Is the MXR Super Badass Dynamic O.D. like a Fulltone OCD?
Reviewers and news writers widely describe it as an OCD-inspired design. Both are MOSFET overdrives with a similar control layout, and Premier Guitar called it MXR's OCD-inspired stomp. Gearnews noted it uses a similar circuit to the Fulltone OCD, though MXR itself does not market it that way.
Is the Super Badass Dynamic O.D. true bypass?
Yes. The Jim Dunlop manual lists its bypass as True Hardwire, and Guitar.com's review confirms true bypass. When the pedal is off, your signal passes without active buffering.
Does the MXR Super Badass Dynamic O.D. run on a battery?
Yes. It takes one 9-volt battery, accessible through a battery door on the bottom plate, or a 9-volt AC adapter such as the Dunlop ECB003/ECB003EU or an MXR Brick Series power supply. Current draw is a low 6 mA.
What does the Boost/Cut switch do on the Super Badass Dynamic O.D.?
It sets the output mode. In Boost mode the pedal increases output level and emphasizes the midrange; in Cut mode it decreases output level. Guitar World's reviewer found it most neutral and transparent in Cut with the Tone knob near the middle.
Where is the MXR Super Badass Dynamic O.D. made?
Guitar World lists its origin as the USA, and Guitar.com describes it as assembled in the USA. MXR is a Jim Dunlop brand.
How much does the MXR Super Badass Dynamic O.D. cost?
Guitar World's review lists it at $129 in the USA, and Gearnews reported the same $129 MSRP at launch. A current Jim Dunlop parts listing shows $139.99, so the figures differ depending on the source and date.
