Tig's hit it on the head.
The quote he found describing the tonal character as an acoustic guitar body wood sums it up. I had a primo Tacoma Jumbo, JK28C, that was positively knee-buckling in tone and volume, not to mention looks.
Bar none, the finest acoustic guitar I've ever owned; but personal priorities and finances forced me to let her go and she found a new home with a fellow fretter a couple of years ago.
These shots show her off; notice the difference in how the koa's figuring plays in outdoor natural light (left) vs. indoors w/ flash:
Sitka spruce top, mahogany neck. Ebony fretboard & bridge.
