If I could have but one piece of gear between my guitar and amp it would be my StroboStompHD. I would have bought another in a heartbeat if mine were destroyed, lost or stolen, and that was before my experience with Peterson CS. Is a tuner worth $139? Yes, if it's a StroboStompHD. Nothing else comes close in terms of performance, function and features. Bonus: Peterson includes unparalleled customer care for free.
