Thank you all. This is all very good advice. I've listened to the Baggs PU and it seemed to break up with fuzz when a full chord was strummed.

I play in an acoustic trad jazz band with banjo, fiddle, keyboard, cornet, clarinet and bass and I need a sound that would be clean when strumming jazz chords on my Martin 0021. I have an AKG condenser mic but I would like to try a good PU that faithfully reproduces the sound of my guitar amplified since I'm playing with horns.

Anyway, that's why I ask.
