Here`s  the bass tab for Kyuss'  "un sandpiper" from their best of record.
It's not complete but you've got an idea of it.
Great song to improvise!

Intro/Main Rriff:

G---------10p8-----------------------
D--------------10-8------------------
A--8--8-8-----------8--8-8-8------8-8
E-----------------------------6h8----

 ----------10p8----------------------
 ---------------10-8-----------------
 -8--8-8-8-----------8--8-8-8----8-8 etc.
 -----------------------------6h8---



some bits of the verse/chorus sections:

G--------------------------------------
D--------------------------------------
A--8-----------------8---------------
E-----1--1-1--1--1-x-----1--1-1--1--1-x

 -------------------8-10--10-10-10-10p8----------
 -----------8h10-10---------------------10-8-----
