Been playing C shaped profiles for most of my life. Recently, I picked up a guitar with a U profile. I know some of the Strats from the 70s had this profile. The profile didn't seem too foreign to me, and the profile seem to fit my hand nicely. Anyone know the history of the U profile, and why they came to be (Fender)? Anyone prefer them over the C profile? Any advantages/disadvantages to the U profile? Thanks!!
