Floyd Rose Speed Guitar is a 513?

[wulftone]

I ran across this fun invention from Floyd Rose and looked over at my PRS 513, realizing I actually already have this practice tool because the middle pickup is basically a little "speed guide" itself. 509 guitar players also have this fun benefit. Lol! It's been fun practicing with it today, thinking about the Troy Grady stuff from the video demo of the speed guide.
