As a guitar player, at first I wasn't sure how to use this thing. It wasn't cheap, but looked fun so I saved up to buy it. It is not intuitive, you have to play with for a while but it can make some marvelously weird noises. You can plug other things into it, too, like drum parts or synth and tweak them. Quite frankly, I will never be able to shred, so "boxes" help me find a unique sound. If they help cover up playing deficiencies so be it.
