Does All Solid Wood Matter? | Martin 000-12e vs. 000-13e

We talk a lot about the importance of (at the very least) a solid wood top on an acoustic guitar, but once the top is solid, how important is the rest of the body? Today we're taking a look at two very similar Martin guitars to put this to the test, the 000-12e and the 000-13e; one of which has a laminate back/sides of Layered Koa, the other having solid Siris back/sides. Can you hear the difference? What tonal nuances can you hear between the layered and solid constructions? Let us know in the comments!
