The BearFoot FX Dyna Red Distortion is an analog distortion pedal from [BearFoot FX] that also reaches into overdrive and boost territory. RockBoard's PedalPedia describes it as having "squeezed the tones from a full Marshall stack" into a single pedal, with high-gain distortion available "with just the twist of the Tone knob" and further shaping from the Volume and Distortion controls1. It sits in the distortion lane alongside other Distortion Pedals, but its range of settings means it overlaps with Overdrive Pedals and Boost Pedals as well.
The controls
The pedal keeps things to three knobs, and BearFoot FX's own description explains how they interact1:
"High-gain distortion with a ferocious snarl comes with just the twist of the Tone knob, with extra tweakability from the Volume and Distortion controls. Go from crunchy, light overdrive as you dial back the distortion to dynamic, roaring distortion when you crank it up."
| Control | What it does |
|---|---|
| Volume | Provides extra tweakability over output level1 |
| Tone | Adjusts the high-gain distortion snarl1 |
| Distortion | Adjusts from crunchy, light overdrive when dialed back to dynamic, roaring distortion when cranked up1 |
That spread is what puts the pedal in the overdrive, distortion and booster categories at once: at low Distortion settings it behaves like a light overdrive, and cranked it becomes a full distortion1.
Power
The BearFoot FX Dyna Red Distortion runs on 5V DC, center negative, and draws 10mA1. That voltage is worth noting before it goes on a board: many players run everything from a standard daisy chain supply, and this pedal's listing calls for 5V.
The BearFoot FX version is specified at 5V DC, center negative, at 10mA1. Match your supply to the version of the pedal you own, because the later One Control 4K version has a different power specification.
The One Control Dyna Red Distortion 4K
The Dyna Red design did not stop with the BearFoot FX version. One Control, which took the design forward, released the One Control Dyna Red Distortion 4k, described by Delicious Audio's Paolo De Gregorio as "an upgrade to the previous Barefoot version of this full-on Plexi pedal"2. gearnews.com called the 4K "a multi-function pedal that looks pretty darn versatile"3.
The current version is sold as the One Control BJFE in Your Hand Series Dyna Red Distortion 4K, and its specifications differ from the BearFoot FX original in a few ways a player should know about24:
| Specification | One Control Dyna Red Distortion 4K |
|---|---|
| Drive voltage | 5 to 15V, center negative4 |
| Current consumption | 3.5mA4 |
| Input impedance | 370k4 |
| Output impedance | 25K4 |
Its controls are labeled differently from the BearFoot FX original, though they cover similar ground4:
- D (Drive): controls distortion intensity and sustain, ranging from subtle to powerful compression for a richly textured tone4
- V (Volume): adjusts overall output level, ideal for balancing the pedal with your amp4
- T (Treble): adjusts high frequencies, perfect for fine-tuning tonal brightness4
One Control describes the 4K as delivering "bold, balanced distortion, adaptable for any amp configuration, solid-state or tube-driven"4. The wider 5 to 15V drive voltage range on the 4K gives it more flexibility over supply choices than the BearFoot FX original's 5V listing14.

Questions
Is the BearFoot FX Dyna Red Distortion analog?
Yes. The pedal's circuit type is listed as analog on its product page, so it processes your guitar's signal with analog circuitry rather than converting it to digital. That matters to players who want the way the pedal responds to picking dynamics and guitar volume changes to stay untouched by conversion.
What voltage does the Dyna Red Distortion run on?
The BearFoot FX version of the Dyna Red Distortion runs on 5V DC, center negative, and draws 10mA. The later One Control Dyna Red Distortion 4K lists a wider drive voltage range of 5 to 15V, center negative, with a current consumption of 3.5mA, so check which version you have before choosing a supply.
Can the Dyna Red Distortion run on a 9V supply?
The BearFoot FX version is specified at 5V DC, center negative, so a standard 9V pedal supply is not what its listing calls for. The One Control Dyna Red Distortion 4K, a later version of the pedal, lists a drive voltage range of 5 to 15V center negative, which does include 9V. Match the supply to the version on your board.
Does the Dyna Red work as a booster or overdrive as well as a distortion?
Yes. The pedal is listed as covering overdrive, distortion and booster roles. BearFoot FX describes the Distortion control as going from crunchy, light overdrive when dialed back to dynamic, roaring distortion when cranked up, which is what lets one pedal sit in all three categories depending on the setting.
