Of course, you could simply go to a store and play one, thereby sampling it. They'd probably let you play it for hours if you needed to. You could probably even get PRS to hand you one when you go there to pick out the next private stock, and ask to spend a few hours with one so you could decide if you like the pickups.
But there will be an NGD post.
You know it, I know it, and the American People know it. The post will have pics, and be complimentary, but somewhere in that post the Seed Of The Rationalization will be sown.
Maybe, as you say, it will be scale length. Maybe the headstock. Maybe the artist grade dirty top is too dirty. But within a few days, the guitar will be Moved. It will be Gone, Vamoosed, Outta there. It will not really be given a chance. It will be unappreciated. "I really like it for playing X style, but I'm not sure about the scale length." Or, "This one's going to be my travel guitar when I go to Canada for gigs (this one is the fastest kiss of doom)."
No, it will not hang on the Wall of Doom for more than a few days. poor thing (I call it the Wall of Doom because a guitar hanging there is ultimately doomed to be cast aside like the wife who stayed with her man only to later find a trophy wife on his arm when she no longer looks the part).
Yes, it's a sad day when the poor guitar finds out your plans, as you lay it in its case, its little heart broken, its dreams dashed on the rocks, to travel to some far flung destination. I hope you feel very, very guilty.
