This is the bass part to Portishead's "Glory Box" from Dummy. It's quite simple and only one string, which is E. G|----------------------------------------------| D|----------------------------------------------| A|----------------------------------------------| E|------0----12--10--10-10--9--9-9--8--7-8-7-0--| And it repeats throughout the whole song. It's much more simpler than jumping from each to another, especially if you might be lazy but you feel like playing.
