Why No Replacement Piezo Elements For Jtv69? in James Tyler Variax Guitars / Workbench HD Posted February 24, 2014 Quick update. Talked to Gray again this AM. He said that they do not currently sell the PN-8002-RO, but that he found 6 individual pieces, matched them (output level, I assume) and has shipped them to me. I'll let you know how things go when they arrive. Nice...but something tells me you're only getting them because it was their fault that the picture and description were screwed up on the site. Anybody else is gonna be out of luck...congrats, tho!
