The 85 is a Bass interval pedal offering studio quality pitch tracking and sound. The 85 gives you independent control of an Octave down and an additional switchable ‘Interval’ control, allowing for an extra octave up, 2 octaves down or a perfect 5th above your original note. Focus control allows you to fine tune the character, from classic funky subs to massive synth-like chords. All with pro level tracking. Powered by 9V adapter (not included). Battery operation is not supported.
