“Does just what it says on the tin, bends the pitch up and down to
create a vibrato effect. It is also very similar to the vibrato effect
featured on the legendary Boss CE-1 Chorus Ensemble and Roland Jazz
Chorus amps. Features three modes (unlatch/latch and bypass) and
rate/depth/rise time controls. In unlatch mode the effect is only
applied when the pedal is depressed, and returns to bypass when
“An amazing effect with a really warm sound. One of
the original advertisements for the pedal apparently stated ‘beginners
should buy after they’ve mastered vibrato’ which is a reference to the
fact that this will require some skill to unlock its full potential.
Original components were the MN3207 BBD with accompanying MN3102 clock
driver (as seen in photo below).”
