John Mayer’s 2015 PRS Custom 22 Private Stock
This guitar was only seen briefly in one of John’s Periscope streams dating back to July 1, 2015 [John Mayer Guitar Lesson on Periscope 2015].
Based purely on the looks, the guitar appears to be a Custom 22 model, but there are few things on it that don’t exactly fit the description. The first is the inlays, which are not the usual “bird in flight”, but Celtic knots styled ones. Second is the fact that all of the hardware is gold-plated, including even the tiniest screws on the back and bridge saddles.
Taking a look at the PRS website, the only model that seems to fit the description is the one branded as the “Collection Series IX – Curly” – which seems to be a really top of the line guitar with all the bells and whistles.
