We're celebrating July the old-fashioned way, the same way your old grandpappy used to celebrate it, with a great sale on used guitar stomp boxes.   Each day we'll feature a different, used effects pedal at a great price, and that price will be good until the pedal sells. If saving bucks on a pedal you'd like to try sounds like fun, then this is the week you've been waiting on. (For most of these pedals, we have only one.  First come, first happy.)

All-New Octave Effects. The OC-3 picks up where the best-selling OC-2 left off, giving guitarists two brand new octave effects. Using the Polyphonic Octave mode, octaves can now be added when playing chords-a first in a compact pedal. More aggressive sounds can be had using the new Drive mode, which adds a touch of distortion to the octave sounds.

If You Loved the OC-2... Don't worry. BOSS knows how much guitarists depend on the original OC-2 sound. That's why the OC-3 includes that classic “dual octave” effect, but with even better stability. This gives you the ability to blend up to three individual sounds: the original note, a note one octave below and one that's two octaves below.

Bass Players Welcome The OC-3 isn't just for guitar, it's also for bass. By connecting a bass guitar to the dedicated Bass input, the OC-3 automatically optimizes itself to suit the range of a bass guitar. Now bass players can upgrade to the ultra-stable octave sounds of the OC-3.
