Mayer sig neck and pups are the highlights of the guitar IMO, not the poly finish body.
Overall, it's a great guitar, just not sure why Fender didn't use thin nitro on body and charge a little more.
Just a thought, but if it's the pickups that are the big draw for you, perhaps checkout my quick noodle of Big Dippers vs Lollar Blonde in either the neck or 4th position pup.....don't recall which pup I compared, perhaps noted on video, but these are the two positions where Mayer mostly lives on/what you hear him mostly play on:

Close enough and Jason stuff is killer.... cost about $275.00 new or take a chance at $300 or more and maybe get fake Dippers on ebay. Just find a killer price on a used EJ and drop in a Lollar Dirty Blondes and resell EJ pups for $250 and you have a perfect custom shop quality guitar with a good pro tech setup. You have options, more than I'm noting here.
Here's some of my JM porn to keep the GAS flowing....

Here's IMO the ultimate Mayer, FCS relic body and hardware, Mayer neck and Big Dippers...

Here's a current new build in progress using only JM neck, but with a tip of the hat to his old sig limited guitar in metallic Charcoal Frost, but faded and over 3TSB...will use set of John Cruz Wildwood pups for this project...

Or this one, Mayer neck and FCS singed Abby pups, not initialed ones....beware, heavy relic porn....
