I can't seem to find that sound on my PA3X, but it does have some excellent distortion and overdrive guitars in it. This sound may be a sample or an edit of one of the guitar sounds.
The joystick, ribbon and DNC buttons can really add realism to the licks. As you all know that kind of Rock isn't really in my usual repertoire, however, I don't believe it would be that hard to do if a person were into that genre.
I am truly honored that some of my peers here seem to think I'm good at guitar emulation. I suppose if you do it five nights a week for 40 years you can better at it!

I do believe the PSR S950 has far better guitar sounds out of the box than the Korg. I also know you can edit the Korg sounds to reach that level, or surpass it, but I'm pretty lazy when it comes to editing voices.
I am torn between the Yamaha and the Korg. I suppose that's why I haven't tried very hard to sell either of them. I may decide by accepting the first good offer I get, regardless of which keyboard. Either will suit my audiences just as well as the other. It's just about comfort level for ME.
I enjoy the controls, vocal processing, drums, Songbook, touch screen, chord sequencer, foot controller, and many of the sounds on the Korg and i hate to give all that up. However I sure like the guitar sounds on the 950. Plus it has a couple of wonderful Pedal Steel Guitars. The Korg has nothing close, but I'm trying to make one on it. I also like the very light, organ-like key touch and the light weight. The Korg sort of balances out the small weight difference by being smaller in size than the 950 though.
I had misplaced my Kodak video camera, but found it again yesterday, beneath the pile on my desk. I will try to make a short video of each and if I like the results will post them. Next time it gets too cold for golf or fishing that is!
I think there are no bad choices in arrangers these days.
