This is my newest guitar. It's a Collings D1 and it is load and smooth. The difference between a D1 and the D1A is the A has an Adirondak spruce top where as the D1 has a Sitka spruce top. The Adirondack traditionally has produced a louder sound than sitka but I played this one alongside another D1A and couldn't tell the difference. Oh, the D1A is $800 more. Thanks to Pete and Butch for helping me decide on this great guitar. The first festival I took it to was Supergrass last weekend and everyone complimented me on the terrific tone and volume of this guitar. It sure looked funny with me picking my Collings wearing a Martin ballcap.
