Fusing classic BOSS octave tones with the latest tracking technologies, the BOSS OC-5 sets a new standard in octave pedal performance. Vintage mode provides a spot-on recreation of the legendary mono OC-2 from 1982, while Poly mode offers numerous enhancements for extended-range playing. And with the addition of an octave-up feature, a span of three octaves is now available for creative exploration. Powered by the latest real-time processing technologies from BOSS, the OC-5 provides exceptional sound and playability for the most expressive octave experience ever. From fat, low mono sounds to octave-shifted chords and more, the OC-5 delivers the widest range, finest sound quality, and best playability in any octave stomp to date. Another cool OC-5 enhancement is the new octave-up effect, which is available in both Vintage and Poly modes. Simply twist the dedicated +1 OCT knob to bring in the desired effect level. Use the octave-up effect on its own for faux 12-string sounds and unique solo tones, or blend it with the octave-down effects for extended chord voicings and super-fat leads.Power Supply: Alkaline battery (9 V, 6LR61 or 6LF22) AC adaptor (PSA series: sold separately)Current Draw: 60 mAExpected battery life under continuous useAlkaline: Approx. 5 hours *These figures will vary depending on the actual conditions of use.Width: 2-7/8 inchesDepth: 5-1/8 inchesHeight: 2-3/8 inchesWeight (including battery): 1 lbAdding value to your purchase, Austin Bazaar bundles your instrument with necessary accessories saving you time and money.
