So I bought RC-1 looper pedal from Boss, and I found out I can link FS-7 to it, so my loops would be easier to handle.
I'm so happy that I bought it.
I use acoustic gitar and electrick bass for my loops. RC-1 made it easy, FS-7 takes it even more further. For example when I loop first a bassline with guitar, and then for the second loop I play a little doodle from higher frets for the chorus, I can just with one mear kick undo the doodle in the verses and with the same kick bring it back for the chorus.
And with the other switch I can pause and play the loop/loops with one kick.
Made my life so much easier.
So if you're considering should you buy this footswitch, I say you really should. Just don't forget the Y-cable.
