Knowing nothing about electrics, but THIS one.....

There was a Belew signature Fly sold on Reverb recently (another blue one, Tom!). This Reverb ad also includes a video of Belew talking about the guitar - but not actually playing it!

Interesting that Bowie used two guitarists who played Parker Flys - Belew and Gabrels...

And the Belew Signature model had built in Midi as well.
