It works fine. Does what you expect it to do.
is connected to the looper with a TRS cable (not a mono jack). I received a TRS cable with the unit, good!
For any electronic instrument, or electric guitar, no problem, you will be very happy.
switches are extremely noisy. Like really really noisy. If you need to record voices or acoustic instruments in the studio, this foot controller is simply UNUSABLE. I bought it, and in the end I only use it for the display. I control the looper with a midi footswitch. For me it's only a very expensive disply :-D
