Old meets new in the most versatile octave pedal yet. The Boss OC-5 is the new flagship octave pedal and sets a new benchmark. Building upon everything good about the previous models the OC-5 incorporates innovative upgrades to deliver the new industry-standard in octave effects. These include a new dedicated octave-up control Guitar/Bass selector switch and variable range control to choose which notes get harmonised. The biggest upgrade however is the elimination of latency so you dont need to worry about any delay between you playing the note and the octave sounding. Boss have upped the game with the OC-5 and created the most definitive octave harmoniser yet. OC-2s big brother Upgrading a classic. When Boss released the OC-2 in 1984 they changed the pedal landscape with a distinctive octave effect that earned its legacy as a cult classic. Now with the Boss OC-5 they have changed the game once again. With Vintage mode selected the OC-5 perfectly recreates all the quirks of the original OC-2 just with a few revolutionary upgrades. No latency is the biggest of these – now you get instant octave response helping your playing be even tighter. Separate controls for -1 and -2 octaves also makes tweaking your sound much easier and youll likely find yourself spending hours dialling in different variations of octave goodness. A true classic reimagined for the modern age. Boss box of polyphonic tricks Among the many updates in the OC-5 is Boss new tracking engine for improved response. When the poly mode is selected these improvements become truly noticeable and youll see instant synchronisation between the octave effects and your playing. This improved response is complemented by a clever new feature which is the Guitar/Bass switch located on the top of the unit. This allows for simple optimisation of your sound based on instrument and again adds a level of intuitiveness simply not found on other octave pedals. The variable range control is what really separates the OC-5 apart from the pack. Giving you total control over which parts of your sound get harmonised certifies the OC-5 as the most versatile octaver currently available. If you want full chords embellished with 3 octave harmony leave the setting at max. However if you only want the bass note affected simply set the range to lowest and only the lowest note of each chord will have the octave applied. This gives you unparalleled control over harmony and gives the OC-5 its remarkable versatility.
