I have two acoustics now; one is an Alvarez-Yairi WY1-K, which is the Bob Weir model, in koa. Aside from being a gorgeous guitar, it is without a doubt the best acoustic for playing out live I've ever encountered. Weir designed it with the entire body laminated, which makes the guitar pretty much impervious to feedback. You can crank a monitor at your feet and play with impunity, which was not the case with the various Takamine and Guilds I've tried it with. It's smaller bodied guitar, terrific neck, very fast for playing lead, and has an action like butter. Just an all around beautiful instrument that is a joy to play. Can't recommend it enough. Fabulous guitar.
It's tone with the onboard electronics reminds me of Garcia's Takamine on Reckoning. I only have the onboard piezo, but you can mount a condensor mic inside the guitar, and plug that into the auxiliary input on the onboard preamp and mix the two together. It sounds pretty good with just the piezo, though. You can see and hear it here during the one and only acoustic set we've ever done:

I thought that would be all the acoustic guitar I'd ever want, but my girlfriend surprised me with a Martin D41-S on my birthday last summer -- I actually proposed marriage to her that night. (I was planning on doing that *before* she gave me the Martin. I had the ring on me. LOL) The D41-S is a typical D Martin dreadnought, big bodied, spruce top, rosewood back and sides. The "Special" refers to slightly different bracing, a V neck, butterbean tuners and snowflake inlays on the fretboard.
It took a while for me to get used to the V neck, it's wide, especially compared to the Alvarez-Yairi. I really like it now. Martin guitars are as light as a feather, and their tone is just exquisite. It has that "piano-like" tone that Martin is famous for, very loud, with nice solid bass, warm mids and ringing highs. It's just a joy to play in a room with good acoustics. I would never take it out and try to play it live, they are so resonant that they are pretty much unmanageable onstage, as Garcia found when he tried to use his D-18 for the Warfield/Saenger/Radio City run in 1980. I always regretted letting my D-28 go to get the Alvarez-Yairi. Lefty Martins are hard to come by. Lefty anything is hard to come by.
