I've looked at the other tabs for this song and I've tabbed a more fretting-friendly version :-

Artist : The Pixies
Written by : Black Francis/The Pixies
Song : Gigantic

This is a simple bass line but still catchy

----------------------------------------------------
----------------------------------------------------
---5--7-7---2-2--3--5-5-----5--7-7---2-2--3--5-5----         etc...
-3----------------------3-3----------------------3-3

This is repeated the whole way through, listen to the song to get the tempo.

      Tabbed by The Dirty Monk
