This is an effects pedal built in August 2025 at a workshop held at Shimamura Music Kichijoji Parco store. It's RAD-style. After building it, I incorporated it into my effects board and used it, but I couldn't fully utilize it, so I'm selling it. Therefore, Velcro is attached to the back. * Body only, no box. * No instruction manual included. - Brand: KarDiaN - Number of knobs: 4 - Knob explanation - Top Left: Volume Top Right: Gain Bottom Left: Bass Bottom Right: Treble Thank you for viewing.
