The amusing thing in that video is that the only comparison that was remotely effective was between the Les Paul and the 594 SC. There wasn’t a meaningful comparison at all between the two 594 versions.
The store owner couldn’t tell the difference between them, though there clearly was one, and also didn’t know the spec for the bridge materials, or even that the plating on PRSes is nickel, not chrome (except for the Floyd model).
These guys are fun, but not very informative.
