I've used a lot of mics inside the guitar and find them all pretty useless in trying to get decent sound. Took about 20 years, but it suddenly dawned on my big idiot head, why would you want to mic the inside of the guitar? All the good shit is happening out front.
When I can't use a mic outfront, for solo work these days, I use a Baggs iMix for my Bourgeois Slope D. It's a great stereo set up getting some bite from saddle pick up and low end thump and ambiance from a well positioned transducer. I've also used a Highlander SP-2 with a Sunrise going through a stereo Pendulum (kind of the classic singersongwriter set up) and just the Highlander in my Martin, which works best for a large band. I alost always run anything through a Demeter tube DI.
Where you going to run when the worlds on fire?
