This amazingly expressive tool is filled with 121 ultra-responsive sounds, all distilled down into a BOSS compact pedal that slides easily into any setup. Best of all, it’s as simple to use as a standard stompbox, so you don’t need any background in synth programming to bring a new world of sonic textures to your music.
