"And then the newest one would be the Slicer, which I picked up last year, right before we started doing the band, and I got that at, I think, Noisebug in Pomona in California, they always have a lot of great pedals, and [it] sort of goes further into like, the things that I was trying to do with the tremolo pedals, you know, but it has these cool harmonic things that happen in it that just don't happen, you know, with tremolos and, again, it's real versatile, and especially the fact that you can tap tempo the whole damn thing, so you can just sort of be changing it up all the time, so it's pretty cool" – Omar Rodríguez-López on the Boss SL-20 Slicer Twin Pedal, 0:55more
