2001 jp6

I am looking for my first EBMM John Petrucci model. I am looking at a Silver Sparkle JP6, and I see from the serial number it is a 2001 model. It certainly looks in good condition although it is getting on for 20 years old. I would be buying this blind as the seller is in the UK and I am in Spain.

As a newbie to EBMM, what should I be asking? What do you guys think from what you see here? I did fancy a piezo but I probably would not use it much so not a deal breaker. What would the pickups be assuming they are the originals and what are they like?

Many thanks!
