Seems Yamaha has come out with a new model of Jumbo acoustic guitar called the FJ Jumbo. Originally in 1960 they came out with the FG acoustic, now they have

FJX730SC - rosewood back and sides
FJX720SC - mahogany back and sides
Both have Piezo  based system 55T pickups

All of which were highlighted at summer namm 2009

This is what they had to say " "Our customers have been asking for a jumbo body offering for a long time," said Dennis Webster, marketing manager, Yamaha Guitars. "Not only have we designed a great jumbo shape, but we've also added the A.R.T. system so that they will sound great out of the gate. Acoustic-electric gigging guitarists have something really great to sing about."

Look to pay around $899.99 for the FJX730SC and FG730SC with ART pickup and around $789.99 for the FJX720sc
