"Musician Ichiro Tanaka, who tuned and played a sample guitar at Gibson's Tokyo office Monday, said the technology is handy for professionals too. If they use special tuning for just part of a concert, as he often does, it means they don't have to lug around an extra guitar with the second tuning ready."
Ridiculous, I have never heard of a professional who considers it a burden to "lug around" an extra guitar.
