DMBTabs

DMBTabs is a place to find guitar tabs (and sometimes videos!) for virtually every single song by Dave Matthews or the Dave Matthews Band (including covers and rare live songs). The drop-down box on the home page allows you to select a specific tab by song title, while the album images allow you to select a song by album (using a mouseover drop-down menu). The site also features an active message board and a gear list. The site's content is created and revised by the site's users, who seem to be obsessively knowledgeable and very protective of their submissions. I'm not very good at playing the guitar, but the site has helped me learn to play a few songs. Overall, it's easy to use and usually pretty helpful.
