Tried mine out last night on headphones.
First impression -cool I like it.
It seems well made but not a must have piece of gear on my list.
I wouldn't have paid full price or even $100, but at $50 it is worth it to me.
I can see this as a useful practice tool in a variety of situations.
I dont get how to put together blues licks in the right key over the right note / measures of the rhythm of a song.
I have to gain an understanding of it, and I can see this as useful once I understand better.
First time I tried headphones in a while, never felt comfortable with the cord, etc.
Seems fine now though.
Oh, and no joke, but no pics, I just had pancakes and a schmoke (vape)!
