Ron & Will, Well, I think we're unknowingly talking about two different things -- a laminated bridge verses a laminated cap. The lousy pianos I'm referring to have laminated bridges -- laminated entirely from top to bottom. Is there a top quality piano using laminated bridges? I think not. Help me here. I would think that a progressive manufacturer like Yamaha would have incorporated laminated bridges if it didn't deflect from the quality level they've already established. Correct me if I'm wrong. Also, I thought that the high production manufacturers machined the notching rather than hand notch. If machined, then it wouldn't make any difference if the cap (or bridge) is laminated or solid.
