Greer Amps Mori Drive Overdrive Pedal
The Greer Amps Mori Drive is a mid-focused overdrive pedal built around a vintage Tube Screamer-style circuit, tuned to sit between classic TS and K-style frequency ranges. It's the sound Greer Amps founder Nick Greer calls his personal favorite take on that circuit — a set of tweaks first reserved for Greer Amps artists before becoming available to everyone. "Mori" is the Japanese word for "forest," a nod to the pedal's organic, woody midrange character.
Why Guitarists Choose the Mori Drive
Most TS-style pedals share a familiar problem: a narrow, honky mid hump and clipping that can feel stiff at higher gain. The Mori Drive addresses both. Its mid hump sits in a more musical, pleasing part of the frequency spectrum, and it puts out more volume on tap than a standard TS-style circuit. The asymmetrical clipping has been tweaked for a smoother, more natural overdrive tone that blends into a pushed tube amp instead of fighting it.
That smoothness is what makes the Mori Drive such a strong stacking pedal. Built around a JRC4558 chip, it plays well in front of nearly any other drive, fuzz, or boost on your board. Pair it with a clean boost for extra push into your amp, or stack it with a fuzz for a thick, textured lead tone. Players who run multiple overdrives report the Mori Drive is one of the rare pedals that doesn't fight for space in the mix.

Who the Mori Drive Is For
The Mori Drive is a natural fit for guitarists who want their overdrive to feel like an extension of their amp rather than a separate effect. Blues and classic rock players will appreciate the smoother clipping for sustained leads, while country and Americana players get a touch-sensitive drive that cleans up nicely with the guitar's volume knob. Because it's designed to stack cleanly with other drives, it's also a smart choice for anyone building out a pedalboard who wants a dependable mid-gain anchor to layer boosts and fuzzes around.
Beginners benefit from the Mori Drive's simplicity, too. With just tone, level, and drive controls to learn, it's an approachable first overdrive with enough depth to grow alongside a player's ear over years of practice.
How the Mori Drive Compares
Compared to a stock Tube Screamer-style pedal, the Mori Drive trades some of that circuit's signature mid honk for a broader, more amp-like voice, with extra headroom and volume on tap. Where many TS clones feel congested when stacked with other gain stages, the Mori Drive's tweaked clipping leaves more room in the signal for a second or third drive pedal — a favorite building block on pedalboards that stack multiple overdrives for solos or genre-hopping setlists.
Frequently Asked Questions
Is the Mori Drive true bypass? Yes. When the pedal is off, your guitar signal passes through unaffected.
What power supply does it need? It runs on a 9V battery or a standard negative-center 2.1mm power supply rated between 9 and 18 volts. Running it at 18V increases headroom.
Will it work with my other drive pedals? Yes — the Mori Drive was designed to stack cleanly with virtually any other overdrive, distortion, or fuzz circuit, making it a versatile addition to an existing pedalboard.
How long is the warranty? Greer Amps backs the Mori Drive with a 5-year warranty to the original owner.
