Up for sale is a highly sought-after, vintage Boss OC-2 Octave pedal, fully confirmed to be Made in Japan in January 1988 (Serial Number: 866813).This is the classic "Black Label" era MIJ version, legendary for its fat, analog sub-octave tracking that modern digital modelers simply cannot replicate. If you are looking for that iconic, synthetic synth-bass growl used by everyone from Tim Commerford (Rage Against the Machine) to Pino Palladino, this is the exact era circuit you want.

Key Vintage Identifiers & Specs:

• Production Date: January 1988 (Serial # 866813 stamped inside the battery compartment).
• Origin: Made in Japan (Features the internal "Product of Roland Japan" stamp).
• Cosmetics: Features the correct vintage black knobs with silver insert caps and the classic white "Octave" text font on a metallic brown finish.
• Power Requirement: This unit uses the vintage Boss ACA circuit. Note that it requires a 12V DC ACA adapter or needs to be powered on a daisy-chain with other 9V pedals to receive the correct voltage (a standard standalone modern 9V supply will make the LED appear dim).

Condition:

• Functional Condition: 100% fully functional. The pots track smoothly, the footswitch engages perfectly, and the classic analog tracking is exactly as it should be.
• Cosmetic Condition: Good vintage condition with some honest player wear, light scuffs, and surface scratches consistent with a pedal of this age (please see photos for exact condition). The back label is missing, but the internal serial stamps fully guarantee and verify its 1988 MIJ pedigree.

Pedal only. Does not include original box or manual.
