GUITAR MUSIC ARCHIVE
www3.wildfire.com/~ag/gma
GMA has been taken down. It will no longer be a repository for tablatures. "It's simple. I can not legally host tablatures for artists who have not given me the right to distribute their works. Going forward, I can not be assured that such material will not be posted to this site so I have stopped providing this service in whole."

You can, however, still get recent tabs at:
Fresh Tabs
freshtabs.hypermart.net

There you'll find tabs like:
Red Hot Chilli Peppers: Scar Tissue
freshtabs.hypermart.net/rhcpsolo.txt
also Californication By Red Hot Chili Peppers
freshtabs.hypermart.net/califor1.txt

You can search the remains of OLGA through Guitar Notes:
www.guitarnotes.com/olga
This once had 40,000 tabs, but many are now removed due to copyright infringement issues. OLGA closed a year ago due to legal threats from The Harry Fox Agency.

The Online Guitar College links to tab archives for nearly 300 artists:
