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.
There are no more simple and user manual is useless!
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!
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.
