The successor to the original Klon Centaur, released by Klon. I've tried various Klon-type pedals, but I still think this one is the best. The density of the drive when boosted is in a class of its own. The used price is also rising these days. If you are looking for one, please consider it. Operation confirmed Original box included Overdrive effector Klon KTR, red, with box. - Model name: Klon KTR - Color: Red - Accessories: Box - Features: Overdrive effector Thank you for viewing.
