Bob Dylan — Knockin' On Heaven's Door bass tabs

Intro: in the intro you can just slide on the Estring to the root 
notes. after repeating, let the A ring then build up and play 
the hammer—on pull—off. this builds up to the main riff of the 
song where the vocals come in.

Main Riff: play this riff during the verse and chorus. its ppretty 
basic, sticking to the root notes but to make it more interesting 
i through some little riffs when the guitar plays the A7 chord. 
to get the timing down listen to the guitar as it plays the chords. 
right before the next chord change is when you through in the 
quick little riffs.

then right before chorus: let the A ring to build up for the chorus.

This is a neat song. if you stick to the root notes you can add inyour 
own little riffs in between chord changes to make it more interesting, 
or just use this tab and add in some more hammer ons and stuff
