I bought this from a recycle shop about three months ago and have been using it with pleasure, but I'm selling it because I'm updating my equipment. It's characterized by a dry sound and a distortion that gives a sense of fine grain. You can get a lot of distortion with just this one unit. The bass and treble equalizers are also quite effective, making it a versatile overdrive. It's a very distinctive effector, being a Kyoto brand, so please give it a try! Velcro is attached to the back. It is a fully functional used item, so please purchase only if you understand this. #overdrive #guitar #effector
