Just saw this one on Guitar Noize. It appears the Washburn N7 7-string that Nuno Bettencourt was rocking on Australian Idol with Rihanna is now available from the Washburn Custom Shop!
According to the Funky Munky Music forum, The stock N7 will have a Seymour Duncan Distortion humbucker in the bridge, instead of the Bill Lawrence L500 of the 6-string version. It will have an alder body, maple neck and ebony fretboard. Price will be $US2799.
