Boy, have I tried EVERYTHING! Over the years I've used magnetic AND piezo. It usually boils down to the piezos being tinny (or feeding back when you bring up the low end) and the magnetic pickups being a little too "smoothe".
I currently use the Fishman Rare Earth (not the blender...cause I'm usually playing into a mike anyway) and I'd say it's pretty good. A bit more acoustic than the Seymour Duncan I was using before.
Willie, I always miked the S-10 (nice to finally have some kind of model number) at the end of the fingerboard rather than in the middle of the soundhole....and I have to say...virtually every sound person I worked with commented on how well the guitar miked. When I miked it in the middle of the hole, I'd have the same problems as folks with D-28s (too much boom). This is why I have to use a Fishman on my D-35.
The "Frets" article "alluded" to "copyrite infringements" with Gibson. I wrote Gibson once about this and....of course, got no answer. Just yesterday I played a 1962 Gibson J-50.(selling for 2600!) and design-wise they are identical....but not sound-wise!
