Because I'm All About the Guitar Pt. 19: Is it guitar or is it Korg?

I am a fan of progressive rock. I love bands that consist of great musicians playing great music at breakneck paces. Odd chord choices and interesting scale progressions are my cup of tea.

A common theme is making one instrument sound like another, or mimicking other sounds. My favorite band, Dream Theater, is big on this with guitarist John Petrucci and keyboardist Jordan Rudess sharing solos. So, I've decided to post a fun little challenge, can you tell which solo is guitar and which is keyboard:

Let me know how you did.
