Here an unusual active Super Flighter SF-600, through neck series made in Japan by Yamaha from 1978 to 1979, these guitars are related to the earliest superflighters SF-500, 700 and 1000 and are well sought after.
The guitar has a 22-fret laminated through neck and a solid maple/mahogany body. It has two humbucker pickups with independent volume and tone controls, and features an active circuit with coil-tap option like the SF-1000, albeit via a 2 microswitch and has a wide tonal range. Good quality chrome hardware and tuners, versatile and solid, and accurate. Rosewood fret board with mother of pearl dot markers. Guitar currently on tour with Bill McGonagle at SinDogs
Great guitar. I still own one of these. Bought from my first self-earned money back in 1982
