They really do - also make great nut and saddle cleaners too. Paint dabbers for gun sights - lots of uses for the remnants. Back to the question - I think the whole thing is about individuality, or maybe the opposite - saw someone else do it and they could play better, so maybe just maybe having a birds nest of strings flopping around their headstock was gonna be the psychological boost to their playing.

I mean aren't we the same people that invest thousands (sometimes tens of thousands) into instruments and amps, drive a $1500.00 beater of a car, travel five hours for $200.00 gig...yeah that's us. I have nightmares of the Ernie Ball Monster tying me up and doing very strange things to me - night after night. The 24P off me banjo gets me every time. Beware of the strings and wear glasses like me!
