Hey everyone, first post here.

I apologize for such a basic question, but I was wondering essentially what the difference between a Custom 22 and an ME Quatro is and what justifies the price difference. I can see a few obvious things, like the headstock inlay, and the wood appears to be different, but it'd be great if someone could help me out.

And one more thing - are ME Quatro's always 22 fret? Is their a similar model with 24 frets? Or would you just settle with the Custom 24?

Again, I apologize for what I'm sure seems like an extremely basic question but I'm new to PRS guitars and couldn't find the answer anywhere else.
