There has been lots of talk about a better bridge making a big difference. What makes a better bridge?
The most obvious is getting the action right, but this can be accomplished with shims or fitting.
The choice of wood is fairly important I gather. Ebony is brighter, even harsh. Rosewood is warmer.
Good fit to the top plate. Easy enough with sandpaper taped to the top and a little patience.
What about shape and mass? These seem like critical factors. What are we looking for? The lightest possible as to be responsive? Slender in section so as to rock back and forth more under the strings?
I ask because I made a new rosewood bridge for my Gitane a year ago and though it is prettier to look at, it frankly didn't seem make much difference in sound. Maybe I was expecting too much. Could it be too thick in section, the top where the strings lay is about 2mm and the fore and aft sides and underside are hollowed out.
