Walrus Audio’s Fundamental Series Drive is the go-to pedal for players who crave versatile overdrive in a compact, no-nonsense design. With a trio of top-panel sliders—Gain, Tone, and Volume—you have full control over your tone. Whether you're after a touch of grit or all-out distortion, this pedal delivers. The Gain slider lets you dial in anything from subtle drive to roaring crunch, while the Tone slider shapes your sound from smooth and warm to edgy and bright. The Volume slider ensures you can go from quiet bedroom practice to stage-shaking levels.

A 3-way mode switch—Smooth, Crunch, and Bright—adds even more tonal flexibility, making it easy to customize your overdrive for any situation. With its intuitive layout and powerful sound-shaping abilities, the Fundamental Drive is an essential addition to any pedalboard.
