This is an Animals Pedal overdrive. It's a Marshall-style overdrive. Please refer to the product page for more details. I liked the dark, damp distortion quality of Marshall amps. Depending on the amp and guitar you pair it with, it may sound muffled, so I personally felt that you need to consider your sound creation to some extent. I had no complaints about this pedal, but I'm selling it because I've started making sounds mainly with the amp's distortion. I will lower the price at my own timing.
