Alvarez-Yairi FYM66HD I don't think there are too many of these, based on their story of a re-discovered stash of 50 year old Honduran old growth mahogany. Once the stash is used up, that's it. There are also a spruce topped Dreadnought and OM in the series. The dreadnought would have been great but I've already got some dreads. I really wanted something different so I got the all-mahogany OM. So different from my other guitars with their big bodies and spruce tops, and that's great because now I have a variety of acoustic tones at my fingertips. Look at that wood, I could almost eat it.
