Boss HR-2 Harmonist Pedal- Taiwan - Sep 1995  (Pre Owned...In Box) AH86295

The Boss HR-2 Harmonist (1994–1999) is a discontinued, intelligent pitch-shifter pedal designed to add one or two voices of musically correct harmony (3rds, 5ths, etc.) based on a selected key. It offers two-voice (A/B) harmonies with up to one octave of adjustment up or down, ideal for creating lush, multi-part guitar lines.

• Intelligent Harmony: Detects the scale of the instrument to output appropriate harmonies based on a selected key.
• Dual Voices: Features independent LEVEL and VOICE knobs for two distinct harmony parts (A and B).
• Operation: Capable of 3-part harmonies (original note + two shifted notes) or 2-part harmonies (using Detune).
• Connections: Includes Input, Output A/B (stereo), and a dedicated Detector In jack.
• Tracking: Known for being an early, accurate intelligent pitch shifter, though it can exhibit tracking inconsistencies

• Adding harmonies to single-note lines.
• Creating thick detuned sounds (similar to chorus).
• Simulating multi-guitar harmonies as a solo performer.

Note: The HR-2 is often considered an "underrated" pedal and was succeeded by units like the PS-5 and PS-6, but it is unique for its specific dual-channel intelligent, harmonizing capabilities.
