I have BOSS DS1 and I´m pleased. A very good pedal (Vai & Satch are using same ones) and the price is outstanding. About 40-50$ Pretty cheap. It´s much 80-s sound over it and I like it. But if you play too heavy music, than it´s nothing for you. Dist is pretty clean so it´s very good for shredding as long as you have none tone our just a little bit. I like it much more than BOSS Metal Zone.
