Hi guys, this is my first ever tab, so feel free to give any criticism. 
I noticed there was no bass tab for this song on the database, 
so i took the trouble of uploading it.
i interpreted this by ear, so hop it's right. 
i have performed this live, and sounds like the original, so it'll do.

and if you would like it in a different key, 

just heighten or lower the strings evenly :)

feel free to contact me on aleckentwilson@nirvanafans.com

enjoy :)
