These are great questions, KLB, and the type that would whip the boys over at the TelePage into a real frenzy..Just curious...
Since the saddles are not adjustable, the intonation accuracy for the wound strings will depend on which brand of strings you use. The relationship of the core diameter to winding size affects the string tension, which affects the necessary intonation position of the saddle required. Also, intonation is affected by how high you set the action and how much neck relief affect you like.
Why not use the adjustable Wilkinson brass saddles on Suhr and other guitars? There is another brand that I can't think of at the moment.
Also, how would you go about choosing a magnetic vs. non-magnetic bridge plate? ($99 to $125 for a bridge plate? Ouch!)
