The 12 things that affect guitar tuning stability
I'll probably do a video on this later because it really needs to be shown (and heard) to fully understand why there is a very specific way to tune certain electrics.
Gibson electrics produced during the "Norlin era" are units produced from 1970 through 1983; these are considered by many Gibson fans to be the worst guitars Gibson ever made, and for good reason - they were in fact awful.
What makes or breaks wanting a guitar or not for many is the finish. Now bear in mind "finish" does not mean the same as "paint". For example a "natural finish" obviously isn't a paint. It could be clearcoat to bring out the guitar wood's natural color, or maybe a stain to slightly darken a wood's natural color. So when I say "finish", I'm referring to paints, clearcoats, stains, semi-stains, "burst" style and so on.
