Hi Cindy,
As I understand it, the Taylor wave compensated saddle is a straight replacement for their standard TUSQ saddle, it may require some height adjustment, but the compensation is the same as the TUSQ (this is what I was told by Taylor Europe before buying the saddle). I don’t have any intonation problems and wanted the bone saddle just for the (possible) improvement in tone.
A couple of years ago I took a trip to Scotland, in order to get a highly recommended luthier up there, to fit a bone saddle to my Yamaha L series. The Yamaha was a nice sounding guitar before the work, but it was significantly improved by the change. Unfortunately, the Scottish option is not available anymore. Now the Yamaha was, at the time, my pride and joy guitar wise and I was very nervous of anyone working on it; the Taylor cost six times as much and the thought of any non-Taylor guitar technician working on it makes me sweat a bit.
So my reasoning was, if I can get a bone saddle that I can just swap with the TUSQ (once the height is adjusted) then I would see if that would bring the same level of improvement to my GA as it did to my Dred. If I don’t like the change, I just put the TUSQ saddle back, and other than the cost of the saddle, I’m no worse off.
