Wampler Moxie

A Classic Revisited: The Tube Screamer Spirit with the "Moxie" Twist

Since the late 1970s, the Tube Screamer family has established itself as one of the most copied circuits for a simple reason: it knows how to "push" an amp like few overdrives, adding mids, sustain, and musical compression. While many pedals focus on the 808 or TS9 variants, the Wampler Moxie OD draws inspiration from the TS10 spirit, a model appreciated for its snappy character and its ability to go from a subtle clean boost to a gritty drive that pushes the amp into a denser overdrive.

The result is a warm and rich pedal, with that extra bite that helps notes stand out, while maintaining true flexibility thanks to two voicings designed for today's musician.

For Which Guitarists and Styles?

The Wampler Moxie OD is aimed both at intermediate guitarists looking for their first "pro" overdrive and at studio or stage musicians seeking a reliable, compact, and quick-to-adjust pedal. In blues, funk, and pop, it works wonders as a light boost to add body and presence, especially with single-coil pickups. In rock, it becomes an excellent crunch engine: you can leave it on as a grain foundation or use it as a stepping stone for your solos.

It is also very relevant in high-gain contexts: placed before a saturated channel (or a distortion pedal), it tightens the attack, clarifies the low end, and brings the guitar to the forefront. On a stacking-oriented pedalboard, the Moxie OD can be placed easily before or after another overdrive depending on the goal: before to push and sculpt, after to raise the level and reshape the EQ.

Controls, Switches, and Design: Simple on the Surface, Rich in Possibilities

The Moxie OD remains intentionally straightforward: three potentiometers Volume, Gain, and Tone to immediately find the landmarks of a "screamer" overdrive. The Gain covers a wide range, from almost clean boost to more pronounced saturation, with a dynamic playing feel and natural compression that makes phrases easier to hold.

Two switches add the versatility that makes the difference. The Voice switch modifies the overall EQ to bring more clarity and a more transparent response, ideal if you find the mid focus too pronounced or if you want to preserve more width (bass and treble) with an already rich amp. The Fat switch introduces a custom MOSFET clipping stage, adding a gain dimension and a more "amp-like" feel, as if the overdrive breathes more and pushes harder when attacked.

Regarding integration, the true bypass preserves your signal when the pedal is off, and the compact format allows it to fit on the most crowded pedalboards without sacrificing effective ergonomics once settings are dialed in.

The Sound

The Wampler Moxie OD's sonic signature combines the warm and singing character of a "screamer" overdrive with a slightly more incisive attack, which helps bends and double-stops stand out clearly. There is a present midrange that carries the guitar in the mix, with pleasant compression that smooths the playing without squashing it.

In a more classic mode, it delivers the typical grain and focus to push a tube amp to the edge of breakup. With Voice activated, the overdrive sounds more open and readable, practical for chords or to preserve the personality of an already expressive guitar. With Fat, you gain a thicker and more energetic saturation, with extra bite and sustain for rock leads and punchy rhythms.
