i was learning bar chords on my guitar one day and just kinda saw the relation between the fourth finger when playing a bar chord on guitar and chord on bass... after i asked my cousin whether my theory was correct (which of course was) i just picked up a bass and thumped away and i knew love for the first time... somehow the feel of the thump and vibrations that goes through the body while playing bass somehow just feels awesome (in a non gay way) ;P
