I would compare a PLEK machine to a skate sharpening machine; the neck of a guitar is suited to the player.
Most pro hockey players are quite particular about how their skates are sharpened...the hollow and rocker to their preference. Some players wish a manual grind over a computer assisted grind...the operator is best to know the customer's ergonomics.

The main problem with skate sharpening machines is not the machine itself, but the failure of the machine owner/operator to inspect and maintain the machine. I suspect that the same applies to PLEK machines.

I wonder how many of Jeff Beck, Jimmy Page, Stevie Ray Vaughan, Rory Gallagher, et al, guitars were Plek’d?

The better question is, how many of them would have if it was available?
