We all know that bridge pins should bisect the bridge top-bridge notch edge. I am finding myself a bit tongue-tied in trying to explain the exact problems (and aural symptoms) that occur when this ideal is not met. I'm not talking about a pin being way, way out on the notch, rather just barely touching the edge (or vice versa). Anyone have a nice clear explanation that will help me be more eloquent when trying to explain this to a customer who has asked me to evaluate a new upright for his purchase? Thanks, Patrick Draine
