Looks like it might be hard to do pick edge pop harmonics with this, at least how I do them. I also change the angle of the pick relative to the string quite a bit when I play, and it is hard to imagine how this would work with this device. It also seems like it would give me a cramp in the palm of my hand after a few hours of playing. Of course, these are just my initial impressions, and certainly not based on any hands on experience. It might be the best thing since sliced bread. I like the idea that the pick part is replaceable, as I am pretty hard on picks. It would be better if a few more thicknesses were available (thicker than a 1 mm), but I get that for a new product roll out you pick a few SKUs covering the most common sizes.
Oh, and welcome to the forum, Jeremy. We like it when inventors and luthiers drop by and hang out. Really the only rules we have for commercial folks is to try to not spam the forum with adverts and stuff. So, sit back, take your shoes off, sit a spell....
