I dont know Phil, but it seems fairly intuitive that a pulse, or wave... or however you want to conceptualize it... traveling down a wire and hitting an end point is going to tend to get deflected by the condition of that endpoint. If its angled as the bridge pins are, it would seem reasonable to assume that there will be some degree of force exerted on the vibrating string on that angle.. How much is another matter altogether... but its rather hard to disregard the data Wapin has assembled on the subject. I was under the impression that Wapins bridge was conducive to vibration in the vertical direction, not horizontal. If Rons statement is true, then the whole thing becomes just that more interesting... and as I said a bit back... it would be nice to see the same kind of frequency data on the Stuart as is available for the Wapin for comparison RicB Ron Nossaman wrote: > > >Consider: > > > > > >The Stuart bridge agraffes steer the string excursion in the vertical > > >direction for better tone and longer sustain. > > > > > >The Wapin bridge modification steers the string excursion in the > > >horizontal direction for better tone and longer sustain. > > > > > >Ron N > > > >------------- > >I think that anybody that thinks he is 'steering' the string vibration one > >way or another is kidding himself. > > > >Phil Ford > > I can't say one way or another.
