This is a clone model of the world-famous KLON CENTAUR effector. It reproduces the core, clear distortion similar to the original. Of course, it's also excellent as a buffer or booster. Kester 44 (including silver) is used for the solder. ★ Can be powered by a 9V battery (included) or a 9V center-negative adapter. Only what is shown in the image is included. This is one unit. Immediate purchase is welcome. We do not accommodate holds, so please understand. We may not respond to comments regarding price reductions.
