don't know if anyone has thought of this: i ya can be I rock god by just memorizing the fretboard, than you could do the same with any other instrument.

you will aslo be a violon-god cuz it has frets... and what if you learnt to memorize each notes on the piano? would you be a chopin-like-god-pianiste-in-45-min?

in conclusion: if his trick is so f**cking good, it would work for any instruments. so therefore in one day or two you could master all instruments... :)

good bye! (i better start right now)
