The GT-100 is a one stop shop. Every pedal you will ever want and need is in this amazing unit from Boss. You can easily switch from a killer metal overdrive sound directly to a fast acting delay to a smooth chorus and beyond in just a few pedal punches. Not having to route chords all over the place or adaptors is a HUGE plus as well! It does take some time to program the sounds you need but once you learn how its a breeze!
