The Meatbox is a subharmonic synth pedal: it synthesizes notes below what you play and adds them to your signal, giving bass, down-tuned and extended-range guitars, synths and even drum machines what Digitech calls "serious sub notes"1. Premier Guitar describes it as "a low-end enhancer designed to add serious sub notes," and unlike a conventional octaver, MusicRadar's review notes it "adds a synthesized sub-octave with a hint of envelope to your tone"21. Originally introduced in the 1990s under the DOD name, it was reissued in 2015 and relaunched under DigiTech in 2023 with the same analog circuit in a simplified, more pedalboard-friendly layout1.
What the Meatbox does to your sound
The Meatbox is not a pitch shifter in the usual sense. It generates a synthesized sub-octave and subharmonic content beneath your dry signal, which is why DigiTech classifies it as an "Octaver + subharmonic synthesizer"3. Tom Cram's 2015 press announcement said the pedal "adds mammoth subharmonic enhancement and low-end power to bass guitars, extended-range and down-tuned guitars, synthesizers and even drum machines"5.
Beyond the sub notes, the pedal can work as a tone-shaping tool. Guitar Interactive Magazine reported that the 2015 version "can also cut frequencies for tone sculpting as an interactive EQ and even produce distortion depending on where the output level is set"6. So depending on the settings, it can thicken a bass part subtly, act as a powerful synth-bass voice, or push an amp into distortion.
The four controls
The relaunch keeps the effect deep but the panel simple: four knobs, two large (Octave and Output) and two smaller (Sub and Low)641.
| Control | What it does |
|---|---|
| Octave | Increases or decreases the amount of low octave added to the signal; turn clockwise for more31 |
| Sub | Increases or decreases the amount of synthesized subharmonic added to the signal1 |
| Low | Increases or decreases the low-frequency content of the output, keeping the extreme lows from overwhelming your amp and speakers1 |
| Output | Sets the output level while the effect is on; higher settings can add distortion5 |
MusicRadar's review adds that the saw wave character of the synthesized voice "can be tweaked via the low and sub knobs"2. In practice, Octave and Sub set how much synthesized low end you hear, Low keeps it usable through real speakers, and Output decides whether the effect stays clean or gets grittier.
Power, bypass and the TRS output
The Meatbox runs on a standard 9V DC adapter or a nine-volt battery1, and the 2015 reissue was built in an aluminum chassis with true bypass switching4. True bypass means the dry tone passes through untouched when the pedal is off, something the original 1990s unit did not do; the reissue and relaunch both include it5.
The TRS output is the feature that sets the Meatbox apart from most sub-octave pedals. With a TRS Y cable, the wet octave-plus-sub signal comes off the tip and the dry signal off the ring, so the two can be routed separately1. Premier Guitar notes this lets the pedal "take on the role of a separate sub-synth, so the deep bass can be sent to the sub-woofer" of a PA while the dry signal goes elsewhere1. Tom Cram's announcement described the same idea: the split sends "the octave+sub... separately from the original dry signal to the PA or a low-frequency driver"5.
To use the Meatbox as a split sub-synth, you need a TRS Y cable. A standard mono instrument cable from the TRS output will not separate the wet and dry signals.
The original and the relaunched version
The Meatbox first appeared in the 1990s as the DOD Meatbox, a pedal Premier Guitar calls "a short-lived and 'misunderstood' stomp box" that nonetheless gained a loyal following; others found its powerful synth-bass sound and multiple controls confusing1. DigiTech brought it back in 2015 as the DOD Meatbox Subharmonic Bass Synthesizer, available from August 2015, built on the original circuit design with updated components and housed in a road-tough enclosure with DOD's classic retro graphics5. MusicRadar reported the reissue "recreates the subharmonic synthesizing and low-end enhancement of the original"4.
In 2023 DigiTech relaunched the pedal again, this time under its own name, at a list price of $169.991. Premier Guitar reported that "it's back with the same earth-shaking tones, but in a simplified control layout that's more user- and pedalboard-friendly"1. The relaunch stays faithful to the original analog circuit design but adds true bypass, which the 1990s original lacked5.
| 1990s original | 2015 DOD reissue | 2023 DigiTech relaunch | |
|---|---|---|---|
| Circuit | Original analog design | Same circuit design, updated components5 | Same analog circuit design1 |
| Bypass | No true bypass; bypassed tone colored65 | True bypass5 | True bypass1 |
| Controls | Multiple controls1 | Octave, Output Level, Subharmonic, Low Frequency64 | Simplified layout: Octave, Output, Sub, Low1 |
| Price | Not stated | Not stated | $169.991 |
Where it sits among synth pedals
The Meatbox belongs to the small family of synth pedals that generate new voices from your instrument rather than filtering or distorting the existing one. Compared with a full guitar synth like the Boss SY-300 Guitar Synth or Source Audio C4 Synth, it does one thing: synthesized low end. Its closest cousins are sub-octave voices like the SubDecay Octasynth and Pigtronix Space Rip, though the Meatbox's TRS split and interactive Low control give it a distinct role as much a utility as a synth. DigiTech's own Dirty Robot Stereo Mini-Synth covers synth lead territory instead of sub-bass.

Questions
Is the Digitech Meatbox true bypass?
Yes. The relaunched Meatbox and the 2015 DOD reissue both provide true bypass, so your tone stays uncolored when the effect is off. The original 1990s Meatbox did not have true bypass, and its bypassed tone was colored, which is one of the differences between versions.
Does the Meatbox run on a battery?
Yes. The Meatbox accepts a standard 9V DC adapter or a nine-volt battery, so it works either way on a pedalboard. The 2015 DOD reissue was also specified for nine-volt battery or power supply operation.
Is the Meatbox analog?
Yes. The relaunched Meatbox stays faithful to the original analog circuit design, and the 2015 reissue was based on the original DOD Meatbox circuit design with updated components. It is an analog subharmonic synthesizer, not a digital modeler.
How do I split the wet and dry signals from the Meatbox?
Use the TRS output with a TRS Y cable. The wet octave and sub signal comes off the tip and the dry signal off the ring, so you can send the deep bass to a PA or a low-frequency driver while keeping the dry signal on its own path.
Is the relaunched Meatbox the same as the original?
The circuit is the same analog design with updated components and the same earth-shaking tones, but the relaunch simplifies the control layout to be more user- and pedalboard-friendly, and it adds true bypass, which the original lacked. The original was a short-lived and, as some have called it, misunderstood pedal.
What does the Sub knob do on the Meatbox?
The Sub control increases or decreases the amount of synthesized subharmonic added to the signal. It works alongside the Octave control, which sets the amount of low octave, and MusicRadar's review notes the saw wave tone can be tweaked via the low and sub knobs.
