Elevate your solos with intelligent, dual-voice harmonies. The Boss HR-2 Harmonist is a legendary "intelligent" pitch shifter that tracks your playing and creates two independent harmony parts based on the key you select. Unlike basic pitch shifters, the HR-2 follows diatonic scales, meaning it stays musically in key with your melody.

This pedal is famous for its "Detector In" jack, which allows you to feed a clean signal directly to the pitch-tracking engine while running your distorted or processed signal through the main input—ensuring crystal-clear tracking even with heavy high-gain tones.

Key Features:

• Dual Voice Harmony: Create two separate harmonies (A and B) simultaneously.
• Intelligent Pitch Shifting: Select your key (all 12 keys available) to ensure harmonies remain musically correct.
• Interval Options: Choose from 3rd, 4th, 5th, 6th, and Octave intervals for each voice.
• Detune Effect: Can be used to create thick, chorus-like "detune" textures.
• Tracking Precision: Dedicated "Detector In" jack for improved accuracy with gain-heavy signals.
• Classic Boss Build: Rugged, reliable, and built to last on any pedalboard.

This is the go-to pedal for guitarists looking to add Queen-style harmonies or Iron Maiden-esque twin-guitar leads to their sound without needing a second player. It features two independent voices and works perfectly for adding depth to solos or creating lush, detuned textures.
