Default Serious vinyl quality control problem?

A lot of the problems with transients though is resonances in the system
between the mass of the arm and the compliance of the cartridge.

I was interested in how heavily modulated vinyl could be, so I popped
an old record (Long Hot Summer Night, Jimi Hendrix, Track Records
1968) under the microscope for a look. And what did I find? Two
adjacent grooves clearly broken into each other:

Was this a really common back then, or is this kind of thing a rarity?


Back in the 1970's Shure sent out marketing people to local stereo
shops demonstrating how good their latest phono cartridge (V15?)
was. The show was great until I brought them my "killer album",
(IIRC Neil Diamond "Taproot Manuscript") which had an extreme
guitar transient in the intro to one of the songs. They never found a
solution to tracking that song. My Stanton at home came closer
to success than their pickup.
