I googled bass tab and found this site http://www.fretplay.com It has both guitar and bass tab. Scroll down and you will see the bass tab. As far as accuracy goes, I do not know if the tab is accurate or not as I have not attempted any of the songs yet. they do say the tab is accurate, though. The good thing is you don't get any of those messages about the tabs being removed. You get the tab when it comes up. But the listings of the bands under the letters are not in alphabetical order so it can be hard finding the band you want. It took me a while to find RHCP tabs.
