Savor Three Flavors of Gain Flexible and capable, the Electro-Harmonix Triboro Bridge pedal gives you three distinct flavors of dirt for any occasion. Three operating modes are on tap — Overdrive, Distortion, and Fuzz — with each mode offering a unique sound. First up is Overdrive, a low-to-mid gain mode that is the perfect “always-on” pedal or boost. Next comes Distortion; it gives you extra gain stages for saturated and crunchy tones. Finally, the Fuzz mode delivers all-out, over-the-top aggression with abundant amounts of gain. Depending on the mode, the Bass and Treble knobs operate differently, giving you plenty of tones to explore. Finally, the compact and pedalboard-friendly EHX Triboro Bridge comes with a buffered bypass to keep your signal healthy.
