I have one of these and am very pleased with it. It's a lot easier to play than the standard Taylor necks. In the past, I've owned a 410 CE and 414 K (Koa with pinless bridge before Taylor discontinued the pinless bridges in '97). Both of those Taylors wore my hand out and forced me to either give up on trying the few songs that I could easily play on my Takamine EF341 using my thumb technique on my fretting hand or use different fingerings that made it more like work than the fun I was just loing for at the time.
This MIM Martin has a Fishman "blender" inside--meaning a saddle pickup as well as an internal microphone which you can switch and blend to achieve a variety of amplified sounds. It sounds very good unplugged too and is light. It's a Martin Xc1T Ellipse. If you use "Martin XC1T Ellipse" as a search criteria on the YouTube site, you will find a bunch of videos of guys playing these. I put a few links below too. They sell for betw $799 and $899.
Taylors are great guitars but my left hand just seems to be clumsy in the open position chord forms at the end of the neck where my playing technique includes using my thumb to "walk" down and up some bass routines. I don't know if it's the radius of the neck or the nut width or what but this Martin lets me do what I like to do and get it right without my left hand tripping over itself and getting tired. Give it a listen. FWIW.
