Thoroughly delighted with my new Stroboclip HD!!! Tremendous value!!! I have been using a well known competitor's pedal tuner for years and I wanted the clip on for redundancy, and to allow me to tune on stage with my volume dialed back but loud enough that I am able to hear what I am doing. As well, I wanted to be able to leave it on while playing and still use the tuner pedal as a mute switch when changing instruments. As I researched the product and the sweetened tuning features I realized that this was exactly what I needed to reduce my tuning frustration! The high level of accuracy appealed to me and found the strobe very quick and responsive. The guitar now seems to stay much more "in tune" over the course of several hours of playing, which I believe is because it is in a better tuned state to start with! I find I am barely referring to the pedal at all. I use the Stroboclip primarily on a Gibson Les Paul, with it "rear facing". The one thing that I would like to see is a bracket that would clamp under a machine head and allow the tuner to be permanently mounted behind the headstock, while allowing it to fold flat against the headstock when not in use or for storage. But, regardless, Bravo, for a fantastic product!!!
