A guitar bridge's most important characteristic is it’s density/weight - it
flexes the guitar top.  Those in the know (not me) would like to have about
30-35 grams of weight, and that becomes a factor when designing a bridge.
Another is its hardness, because it is transferring sound, so that would be the
biggest potential negative for me.  The supplier says that Titebond glue will
hold it to the redwood top just fine.
