I put a Fishman under the saddle pickup in mine. I like it, but it really needs a separate preamp (though the claim is that it doesn't). It is very hot and it's hard to balance when playing with folks who are only using mics.If I had to do it all over again, and if I had an additional $150 to do it with, I'd use a blend of internal mic and under the saddle pickup.
Hope that helps!
