This site is the only site that i have found solely dedicated to 311 tabs (and lyrics with the guitar parts)... i have been using it for over a year. it is about as precise as a site can get when all the tabs are made from people at home trying to figure out the songs. there are small mistakes in each tab, and large ones in some, but this is part of a tab site, and they are easy to figure out given the basis that the tabs provide even though they arent exact. this site also has every song by 311 (from their days of unity, dammit, hydroponic, etc. to unreleased tracks from each album, and even stuff from their newest album, and unreleased tracks that come with their newest video)... check out this site! d

This is a great straightforward website with almost every single 311 tab, including rare songs. There are some errors in some of the tabs, but most of the tabs are great anyway.
