An interesting idea, but not convinced, as they don’t look very adjustable for height, for example, my Tele pickups are higher on the treble side, compensating somewhat for the higher output of the bigger strings. You could cut this into the mount, but that defeats the purpose of being able to test things quickly, the moment one variable is fixed, you have an instant constraint. This experiment is a trade-off, I get that. He’s not an experienced guitar player and wants to fiddle with pickups. Fine, enjoy, EVH was all about getting the sound to match what’s in his head anyway, whatever it took.
