Didn't you make the notches parallel to the top bridge, or did you notch perpendicular to the strings? If the top bridge is wood, I'd make a new one to accommodate the notches in the lower bridge. If I was just replacing a bass bridge on a vertical piano without any other extensive work, I'd just bevel it like it was originally. >My question is: would the benefit/difference be audible - would it make >for a better piano to the discriminating ear? With the deviation as a percentage of overall length, and with the erratic nature of wrapped strings, it's doubtful. Still, if this happens to be the M&H you're putting all that redesign work into, it should be as clean as you can make it. >I should think the difference would be much the same as on a grand that >has agraffes in the bass and the bicord area of the bass bridge is at a >fair angle to the strings and is upgraded from a continuous single bevel >to proper notching.
