Tech 21 Tri-O.D.
Tech 21 · pedal
The Tech 21 Tri-O.D. is an all-analog three-mode overdrive from Tech 21 of New York, covering light, medium and heavy overdrive voicings in one enclosure. The lower setting gives a warm, transparent low-gain drive for pushing a valve amp, the middle setting a midrange-forward crunch, and the highest setting a thicker, more saturated distortion. Each mode is independently voiced rather than a single circuit with more gain applied, and the pedal follows Tech 21's amp-like analog design approach with tone shaping intended to stay responsive to picking dynamics.
