This budget octave pedal adds beef to your sound by generating notes one and two octaves below what you're playing. Want to make a guitar sound like a bass? Or make a bass sound like a dirty synth? This pedal should do the trick! The Range switch dictates whether the low, mid or high frequencies receive the octave treatment, and the 'Direct' knob and two 'Oct' knobs act as dry & wet controls.
 
Powered by a 9V battery or 9V DC power adapter. True bypass.
