The Mozztronics GD-1 Bone Breaker Green Drive is an overdrive pedal that packs five clipping arrangements into one box. Guitar Pedal X describes it as a 5-in-1 multi-drive built around a TS808-style voicing, with clipping modifications added to deliver TS808, OD-1, Guv'nor, OCD and AC30 tones1. Pedal of the Day frames it the same way: a good old overdrive that gives you five different Screamer-esque options to choose from2.
The Mozztronics GD-1 Bone Breaker Green Drive is, by one published reviewer's account, "no one-trick pony, trust us," bringing several vintage sounds together in one place12.
The controls and the 5-way mode switch
Pedal of the Day lists three knobs: Gain controls the gain in the clipping stage, Tone controls the balance between treble and bass in the output (beefed up for a wider range than usual), and Volume adjusts the overall output of the pedal2. Guitar Pedal X's rundown of the controls differs slightly, listing Tone, Body, Gain, Mode and Volume, so the two reviews disagree on whether there is a separate Body control1.
The Mode control is a 5-way switch that selects the different clipping modes2:
| Position | What it gives you |
|---|---|
| 1 | Classic TS type sounds2 |
| 2 | Classic OD-1 type sounds2 |
| 3 | Classic "ello Guvnor type sounds2 |
| 4 | Classic obsessive compulsive type sounds2 |
| 5 | A Mozztronics special, using the clipping arrangement from their DL30 Driveline pedal2 |
Guitar Pedal X lists the same five as TS808, OD-1, Guv'nor, OCD and AC301. The OD-1 voicing uses asymmetrical clipping diodes, which the reviewer singled out as a favorite1.
What reviewers said
Pedal of the Day's verdict was that the GD-1 Bone Breaker Green Drive is no one-trick pony, bringing several vintage sounds together in one place2. Guitar Pedal X's Stefan Karlsson, reviewing in March 2026, praised the OD-1 and Guv'nor voicings while finding the TS808 and OCD modes less impressive1. His preferred settings: Tone, Body and Gain all at 3 o'clock, Mode on 2, 3 or 5, and Volume at max1.

Availability
The GD-1 is not a pedal you will find on every store shelf. Guitar Pedal X's reviewer bought his on Reverb.com from the Australian dealer Found Sound, which he notes also has a decent selection of other Mozztronics pedals1. If the Bone Breaker interests you, it sits in the wider family of overdrive pedals, and Mozztronics' range also includes tube-based designs like the TD-1 Tube Driver.

Questions
What are the five modes on the Mozztronics GD-1?
The Mode switch selects five clipping arrangements: position 1 gives classic TS-type sounds, position 2 classic OD-1 type sounds, position 3 classic Guv'nor type sounds, position 4 classic OCD type sounds, and position 5 is a Mozztronics special using the clipping arrangement from their DL30 Driveline pedal. Guitar Pedal X lists the five as TS808, OD-1, Guv'nor, OCD and AC30.
Is the GD-1 Bone Breaker a Tube Screamer clone?
Not exactly. Guitar Pedal X describes it as a 5-in-1 multi-drive built around a TS808-style voicing, with clipping modifications added to deliver TS808, OD-1, Guv'nor, OCD and AC30 tones. Pedal of the Day calls it an overdrive with five different Screamer-esque clipping options in one pedal, so the Tube Screamer circuit is the starting point rather than the whole story.
What does the fifth mode on the Bone Breaker do?
Position 5 is a Mozztronics special, using the clipping arrangement Mozztronics uses in their DL30 Driveline pedal. It is the one mode on the switch that is not a nod to another maker's circuit, and Guitar Pedal X's reviewer counted it among his preferred settings alongside modes 2 and 3.
Where can you buy a Mozztronics pedal?
Guitar Pedal X's reviewer bought his GD-1 on Reverb.com from the Australian dealer Found Sound, which he notes also carries a decent selection of other Mozztronics pedals. The reviewer gave the price as $219 and equivalent as of March 2026.
