        Could you share how it is you're measuring 1.5 degrees of bearing on 
the bass and with what. If the rear string length was 8 inches( possible on a 
D) 8 Times .026=.208 or (1.5 degrees) of distance bearing . Considering this 
bass bridge has no cantilever  I don't mind seeing this at the top end of the 
bridge but I'd like to see .05 degrres in the mono section. That being said 
I've seen D basses set up with more than that that sounded great and ones 
with nominal bearing or none that sounded somewhat  weak. Where's the beef?
  What's really there has or will come to light with the strings off no 
doubt.
