This pedal does what it's supposed to do: switch between channels on your amp. BUT! Major flaw: it does not switch immediately. It depends on how fast you release your foot from the switch before it switches to the other channel. Very annoying in live situations, or when you immediately want to change your sound. It's bigger brother, the FS-1 has a clicking footswitch, and does change the channel immediately. I bought the mini to gain some space on my pedalboard, but the regular FS-1 is coming back on. The mini - to me - is useless in a live situation. Also, when you stomp your foot on the mini, it's a bit unstable.
