Paul Riario has been the tech/gear editor and online video presence for Guitar World for over 25 years. Paul is one of the few gear editors who has actually played and owned nearly all the original gear that most guitarists wax poetically about, and has survived this long by knowing every useless musical tidbit of classic rock, new wave, hair metal, grunge, and alternative genres. When Paul is not riding his road bike at any given moment, he remains a working musician, playing in two bands called SuperTrans Am and Radio Nashville.
