Behringer UO300 Ultra Octaver

An ultra-affordable polyphonic-style sub-octave generator based on the classic Boss OC-2 architecture. The UO300 adds massive bottom-end depth and weight to your tone by generating notes one and two octaves below your original signal, making it an ideal choice for fattening up single-coil guitars, driving synth-like lead lines, or thickening bass rigs.

Key Features & Technical Specs:

  • 3 Independent Level Controls: Direct (blends clean signal), Oct 1 (one octave down), and Oct 2 (two octaves down).
  • 3-Mode Range Switch: Tailors tracking and frequency response across High, Mid, and Low modes for optimal performance with guitars, basses, or keyboards.
  • Compact Footprint: Lightweight, durable enclosure featuring a status LED for effect engagement and battery check.
  • Power: Powered by a standard 9V DC center-negative power supply or 9V battery (not included).

Condition & What’s Included:

  • Condition: Very Good. Fully tested and 100% operational with minimal cosmetic signs of prior use.
  • Included: Pedal only (no box, ships securely packaged).
