Hello guys, have realized my stock Jim Dunlop slide is no longer doing it. It used to work well for me but I've started mostly fretting the sixth string and the JD is just too long.
My ideal would be: 19mm internal, concave shape (Les Paul profile), 45--50mm, pyrex. Given my slightly unusual tastes I'm going to get a bottlecutter and try making my own, but I'm guessing that someone out there makes something suitable off the shelf.
