This is a top-of-the-line overdrive pedal, popular as a booster. It was likely used by guitarist Ichiro and others. It has a tube-like distortion, responds well to picking nuances and guitar volume, making playing the guitar fun. I think it's a valuable piece of equipment that allows you to enjoy a vintage nuance and soft touch, unlike the transparent pedals that are currently popular. Personally, while the convenience of being able to complete everything with a single modern multi-effects unit (Line 6 HX, Quad Cortex, etc.) is great, I often feel a certain hardness in the sound or a lack of enjoyable sound when playing, depending on the environment. In such cases, I used this effector because it suddenly transforms clean and crunch sounds into a textured sound with a vintage amp feel, even when using a modern amp or PA system.
