Akai UB1 Unibass Harmonized Bass Distortion Unit. Like the Deep Impact, this pedal is no longer in production and is highly prized by both players and collectors. Rarely will you see a unit in mint condition with the original box and AC adapter. I got this from the original owner and haven't used it except to confirm that it is in perfect working condition. Description for manufacturer's website www.akaipro.com: The UB1 allows you to add an octave above whatever you play on your bass to keep the rhythm sound full while your guitarist wails away on lead. You can also add a 5th above (or a 4th below) the octave to retain the feel of guitar 'chords' underpinning your guitarist's deft pyrotechnics. Furthermore, you can add distortion to the harmony to complete the illusion. Operation is simple. Set the controls as necessary and, at the appropriate moment, engage - your bass will not only drive your band along but it will also generate unison and/or chordal guitar accompaniment filling the hole left by your guitarist's solo. Features: Add an octave above what you play so you can simulate the sound of bass and guitar playing in octaves Add a 5th above or a 4th below the octave sound Powerful distortion for the sound of an overdriven guitar Separate outputs allow you to route direct bass signal to a bass amp and effect signal to a guitar amp Email for pics.
