I like Taylor guitars, to the dismay of some LTG's here :wink:, but have never been a fan of the sound of their dreds.
I tried many, but when it came to buying a dred, nothing beat the Guild sound for my ears.
I bought the D-55.
You could probably get a used Guild D-50 or DV-52 with rosewood for about the same price or less than the Taylor 410 with the ovankol - yea, ovankol sorta kinda somewhat sounds similar to rosewood - but not really.
A minor issue, but to me, the shape of the Guild dreds is more pleasing that the shape of the Taylor dreds.
Regarding the expression system, I have a 2003 and 2006 in my Taylors and have never had any problems. There is a lot of negative press for the ES on the Taylor forum part of AGF.
I don't doubt that the folks have had problems, but there have to be many, many thousands, like me, who have not had problems.
I plug into our church PA or my Shenendoah amp and with some EQ tweeking, get a great sound.
