I thought I was going to have to get a wide groove spherical mono tip. Most if not all of my Mono LPs appear to be made in the 50's, 60's 70's and there is not good info given.
i.e. the Chicago South Side Jazz, Vol. 1 was a collection of music from the late 1920's, early 1930's, but it was produced in 1971. Smooth appearance, looks like a currently produced LP, hard to see the tiny grooves exist.
I play it with my elliptical or microridge.
I imagine playing a modern shibata variant in an old wide groove could cause damage and not be expected to sound good either, maybe even an elliptical would be 'wrong'. ?????
