The Mod Chorus is a versatile chorus pedal with three algorithms: chorus & vibrato, ensemble, and flange. It features four streamlined controls for level, depth, rate, and feedback adjustment. The pedal offers three different modulation shapes: sawtooth, sine, and ramp. The Mod Chorus allows players to modulate the modulation effect further with techniques like delayed vibrato, resonant chorus attacks, and an accelerating jet engine effect.
