Here's _Poetry and Prose_ by Primus, from the Beavis and Butt-head album.
This is how I play it, most likely not how Les play it. This is a
passable approximation. Feel free to make corrections. And as usual,
listen to the album to get the rhythm down. Sounds OK to me...

The bass is similar to the guitar:

|---------------------------------------------------
|---------------------------------------------------
|------7---7-----8-8-7-7-6-6-5-5-------7---7--8--8--
|--0--------------------------------0---------------

Also, there's another part the bass has:

|---9-9-9-9-9-9-10---9-9-9-9-10-11-----9-9-9-9-9-9-10----9-10-11---9-10-11-
|---9-9-9-9-9-9-10---9-9-9-9-10-11-----9-9-9-9-9-9-10----9-10-11---9-10-11-
|--------------------------------------------------------------------------
