Exactly. Top-wrapping creates a shallower break angle over the bridge saddle, since the strings pass from the top of the bridge instead of halfway through it, and many players report that their strings feel looser and slinkier as a result. The idea is that with the shallower break angle, the strings are free to move more easily over the bridge when you bend. But it's true, it is very unusual to only do it for part of the strings!Yeah, the player wanted less tension in the 3 bottom-most strings...
I was thinking the same but I think now he had to bring the bridge very down due to the top wrap of the 3 bass strings.Also, I always bitch about string-break height, but does anybody think that the tune-o-matic bridge is pretty low?
