A really cool old Pearl Octaver
three octaves including the original signal in the mix! (Octave +1, Octave -1, Octave -2).The tracking is solid for the octave down, and the octave up is really subtle and natural sounding. The octave sound you can pull is huge! Whether you want to get a really deep low end, or emulate a 12-string guitar, the Pearl OC-7 is a one of a kind octave pedal that really goes the extra mile.
