This is a subtle EQ, which is nice because some EQ sounds nasty until you dial it in. Turn the Volume up to get a little grit, but I use the Volume to send a perfect level into the next pedal. In fact it does wonders for my Eric Johnson Fuzz in cleaning it up. Give an okay amp some Mid range warmth and use the toggle switch to pick three different amp-like sounds that are all very usable. In fact they each make you want to play differently, it's not just a color added to your sound. This is the first pedal in my chain because the EQ is more apparent that way. I'll always have this on my board!
