Thanks guys. What I can't figure out is what note is being played for the two thump-thumps. I think that is the bass line; just those two thumps. (This would explain the possibility of my remembering the entire bass line without having to refer to a tab!)
(There might be another third, higher-pitched thump under the cymbal crash during the chorus.)
Sometimes I think G# (E4) sounds right; the next time I try it might be F# (E2), or even the low C# on the B string of a 5 string. Every time I have tried to nail it down, I end up with a different note!
Slamingerrrr, please listen to this song (link above) and post your two cents worth. Even knowing what the guitar is playing would be a big help. Very simple bass line but I can't figure out what note is being played. Cheers.
