Sorry if this is really simple and I'm just too new but:
I am learning Cliff Burton's (Anesthesia)-Pulling Teeth or at least the first 2 minutes so far. However, I can play it but not get the distortion sound. Some say it's just wah but I can't seem to get it. At 0:39 and about 0:41 when he bends... I can't get it.

Its a Fuzz and a Wah pedal. You can hear him using the wah on the bass parts in Call of Ktulu, also.
