The rhythm guitarist in my band bought one as it is a lot harder to get it to sound good then it looks in the video.
You have to re-learn how to play guitar. If you play chords, you need to play patterns of root, third, fifth to get them to sound good. Single lines aren't bad, but it likes the middle strings a lot more the the high strings. Also, no sliding or bending as it doesn't like that at all.
We're still trying to work it into the band put I think we'll get there if he sticks with it. (Not sure he will.)
