I'm really liking them on my new K24ce. A nice balanced tone.....pairs well with the koa.
I agree...perhaps the HDs are part of the concoction that makes that hardwood top ring out. My new K24 sounds very "alive" as compared with koa-topped guitars I have played in the past. I'll have to try HDs on some of my older Taylors. I believe that they'll do quite well on my sinker redwood/ovangkol BTO for starters.
