Fantastic little thing. It really EQs a guitar nicely to get that acoustic-like sound. Takes that slightly anemic electric-guitar sound and gives it the life, chime and body that acoustics have. The three modes, piezo, standard, jumbo, all sound distinct and different. Perfect for solo use or in a band with 2 guitars when you can't or don't want to switch to an acoustic guitar. I use it all the time, sometimes even doing unorthodox things with it like using it together with an octave-pedal and/or distortion/drives. 4/5 points in sound department, not because it sounds bad, but because it makes a small popping sound when clicking it on. I can live with it, but if you record a lot you might take it into account.
