http://jacksonguitarpalace.com кстати этот вопрос не однократно поднимался. Вот итальянец спрашивал, в созданной им теме: "Headstock problem" Hello Guys, I have just noticed a strange thing on the headstock of my Rhoads:
Ответ - Yeah, basically brand new. That should definitely be covered under warranty.
Check your little booklet/hang tag thing that came with the guitar. It should have information on how to contact FMIC for warranty inquiries etc.
Let us know what you find out.
И т.д....
