NIB rocks and that's no B.S.
NIB is one of my favorite bass lines ever! 'Bassically' features;
1. String bending technique
- 1/4, 1/2, and full step bends
2- Use of effects
- I don;t just mean the phaser, playing wise, Geezer has a great sound from plucking a P-bass close to the neck and use extreme EQ settings to get 'scooped' mids
3 Composition
Most (maybe all) of this tune is based on a penatonic minor. Nothing complex, but I'm one of these "old school" guys who think a solo should be melodic as oppsoed to be a display of Wootenistic tecniques!
Geezer use of distortion and an envelope filter to really add to the song.
Do any Sabbath experts know what kind of envelope filter was used ?
