Yes, some people do indeed find the angle more ergonomic than the flatness of a Fender Strat or Tele. ^^ The Warlock is pretty similar to my LP.
Oh yeah, adjusting a traditional wrap bridge is a pain in the arse

. When doing the intonation, it's best to detune the strings, otherwise you can crossthread the little grub screws and strip the slot for the key.
Looking some more at oldie SGs, there was some variation through time, but a lot of them generally had a lower neck pitch. Maybe this was also done as an attempt to have that slicker guitar that was more competitive with a Strat at the time.
This '64 is pretty much bottomed out, lots of forward tilt due to grub screws being significantly extruded:
Yet, this '63 has a good bit of adjustment left:
The early Standards and Customs also had issue with this due to the sideways vibrola, which had minimal break angle at the back, and the ABR also being set fairly low. Maybe in those days of flatwound 12s it was less of a problem. This is a cool '60 (no, not a typo); would need the Mojoaxe vibrola stop to bring out the best, I expect, with a regular set of 9s or 10s.
