I've been playing for 33 years, acoustic and electric. I have a Taylor K20 which I love for recording. Not so loud in a bluegrass or all acoustic ensemble, but that's ok.
I'm also a producer and own a sweet studio in New London, CT. I want to share this video I've recently done with a guitar expert comparing controlled recordings of four very nice guitars: My K20 which is all koa, a Taylor 714ce (rosewood back/sides, engelmann spruce top), a Santa Cruz Roy Southerner (mahogany back/sides, sitka spruce top), and a McPherson 4.5 (beeswing mahogany back/sides, adirondack spruce top). We show the spectral analysis of each recording so you can visibly see the difference the wood makes (we hypothesize anyway) and the tone of each guitar.
Very interested to get your feedback on this. Here's the link:
