I got the Moxf6 and decided to get the original bag. The keyboard fits the bag, almost too perfect. Theres a large pocket on the front. I would have prefered 2-3 smaller pockets. My pedals and powersupply lies in a pile, and not organized. Also I don't think that the bag is padded enough. The keyboard is not protected enough. The bag has backpack straps for easy transportation. That is great, but it would be nice if they were removable. All and all it does what it's made to do, but for a great keyboard like the Moxf, Yamaha should have made the original bag with more features and in a better quality
Having used several generic keyboard bags for other keyboards I felt it time to get a bag designed for one of my keyboards. It is a snug fit, I particualrly like the shouder straps which enable me to kay the keyboard leaving both hands free to carry other stuff like stands and amps etc. I just hope it stands up to 'life on the road' only time will tell.
