This one will be whatever comes off the line today, if any, so it would be a 513 with the birthdate of 5/13/2013. I do have my eye on a Private Stock though. That one over at Wild West with a maple neck, cocobolo fretboard, and a maple capped black walnut body. It sounded pretty interesting in the video, and the back looks killer. The front is kind of blah with almost invisible 14kt gold hollow birds and a McCarty burst, but it probably looks much better in person.
I am still thinking about doing the 513 take on an early CE-24(maple capped alder body) with a flamed maple neck and a rosewood fretboard. The black walnut has got me thinking again.
