My first White Stripes album ( Had a Barnes & Noble card burning a hole in my pocket) and picked it up based on hearing the album on amazon and liking the overall sound. I listened to it and enjoyed it alot, last night as i was putting it on my ipod for work I was looking through the sleeve and noticed that they don't have a bass player ( I knew they were a duo but figured jack played bass on the album) how the hell do they pull that off ? I mean on the slower songs I see they use piano in the bass's place but on the harder stuff, how does that work ? Detuned guitar?
