I agree. I think it’s placement could cause association with only wrist motion but it could be a tool used for learning lots of motions.
I think recognizing that (barring literal uncommon physiological barriers) finding out that you DON’T have to spend 40 years practicing against a metronome to develop a picking technique that will get you into the (at LEAST) 150-170 BPM range for zipping through some lines is super refreshing.
Finding out that in order to learn to shred (even a little!) you don’t need 40 years experience, just the knowledge that if you can’t get it to work briefly at all, switch it up until you can, is unexpected too
