Acoustic guitars are made out of wood by humans. I've played Martins that suck, Taylors that suck, and Gibsons that suck. I've also played all of the above that decidedly don't suck. The only new Martins I've played that were any good were top of the line $2500+ models. All of the new Gibsons I've played suck, but some of the older ones rock. For brand new off the rack, as Light says, the set up on the Taylors is usually pretty good. I've got a Taylor 710CE with the Fishman stereo blender that has plenty of bottom end, enough to wipe out mics and pres with boom if it's not managed well. I have played a bunch of Taylors that do lack bottom end, though, so I know what you guys are talking about.
I play a lot of strumming with light picks and a lot of fingerstyle, but not heavy flat picking, so I guess I'm not a bluegrass guy. Of course, I would love to own and play the kind of badass vintage guitars Light is talking about, but I needed a car instead. The high end Martins are very good guitars indeed, but I do get the urge to hug a tree every time I play one. In the end, my 710 does everything I need a dreadnought to do. but it's not Taylors vs. Martin vs. Huss and Dalton vs. Froggy Bottom etc., it's *that* guitar, *that* piece of wood. That particular Taylor blew everything else I could lay my hands on out of the water, but at the end of the day, the #2 choice was a Martin D-35 that came in ahead of a hell of a lot of Taylors, and many other brands as well. The Breedloves won bigtime in the bang-for-buck category, but after playing about 100 acoustics, I still came back to that one particular Taylor. My conclusion- it's not about the brand, it's about the particular guitar, and the job you need the tool to do.-Richie
