KNA SG-2 or AP-2 / Fishman Neo-D / Seymour Duncan SA-3HC pickup
 

Anyone have experience with any of those pickups any thoughts? Insights? Any other recommendation on passive stick on/soundhole pickups? Not interested in pickups that needs to modify the guitar in anyway (no drilling etc)

Passive soundhole pickups are my favourite style of pickup for an acoustic, I've tried most of them out there including these three. In order of preference, it's Fishman > Seymour Duncan > Kremona.

The Fishman Neo D is sonically in the middle ground between acoustic and electric hollowbody guitar, but the other two lean a little more towards sounding like a hollowbody. If you want a more acoustic sounding option, the Lace Sensor California and LR Baggs M1/M80 are as good as this type of pickup gets. I have a preference for the Lace option because it's very small and light but still sound fantastic; the LR Baggs are possibly a little better with the string-to-string adjustability and body sensor coil, but I think they're heavy and the trade-off isn't worthwhile when I play unamplified 95% of the time.
