BOSS OC-2 Octave (1991 - Early Taiwan / ACA Spec)

Overview The BOSS OC-2 Octave is an iconic, industry-standard analog octave pedal revered for its warm, fat, and synth-like sub-bass tones. Produced in 1991, this unit represents the desirable early Made in Taiwan (Black Label) era, featuring the original ACA power adapter specification. By blending the original direct signal with OCT 1 (one octave below) and OCT 2 (two octaves below), the OC-2 delivers an unmistakably thick, organic analog character that modern digital octave pedals simply cannot replicate. It remains a legendary favorite among guitarists, bassists, and synth players worldwide.

⚠️ 【POWER SUPPLY SPECIFICATION NOTE】 This early 1991 unit requires a BOSS ACA adapter (12V unregulated) or a standard 9V battery to operate at optimal voltage. If powered by an isolated modern 9V PSA supply on its own, the LED may appear dim and headroom may be reduced (unless daisy-chained with other standard 9V pedals).
