Expression pedal allows you to control the speed of the Dunlop Uni-Vibe continuously.
It has a `micro switch ct heel which allows enabling / disabling of the effect from the pedal.
Completely analog, it simply availing oneself of a stereo output jack.

UTILIZATION

There are no more simple and user manual is useless!

SOUND QUALITY

The amplitude is high enough for some rglage thus developed the speed and the pedal has a `rglage flexibility to adapt each user .. The on / off switch is very sensitive So be careful!

OVERALL OPINION

I acquired it at the same time as the uni-vibe and for me it is essential!
In nine, it is not given but hey I got it used ...
Make the election again .... no problem.
