Yeah I am definitely keeping the EJ Strat. Now, I MIGHT decide to sell the Gibson and put the money towards the JS2450 ( I really want the 24 frets : )
But instead, as someone else here said, its always good to have a neck through the body, solid tailpiece guitar like a LP for any guitar player so I'm probably going to hang on to the Les Paul as well.
If you have the space and the cash, keep all three.
My house, 800 square feet, is small so I have my jazz hollowbody, my rock solidbody, and my acoustic guitar. I have a tiny practice amp and may get a mid-sized combo so that's it and any more spending will be on software to record. If you have the space, keep on buying because there's no way you know what the future holds. I have a friend who works for Facebook and didn't want to miss that opportunity and moved from his cushy life in his country to live in the crime ridden Mission District of San Francisco and pay ten grand a month rent for that privilege to see Zuckerberg in action which I suppose is a once in a lifetime chance. Another friend who had great gear joined the Navy so all stuff was sold and given away and there was no real option for a single man to hang onto it easily being in a different place all the time.
The Eric Johnson is cool in that it's basically a 50s body and neck, but with the aspects of a newer rosewood 60s fretboard. But the pickups are neither 50s or 60s but a special wind that EJ has for his sound. But since he's considered a shredder, the 7.25" inch radius of 50s/60s Fenders won't do, and neither will the sometimes 9.5" inch vintage neck but mostly 9.5" modern neck suffice, either. He has a very, very flat for Fender 12" inch radius fretboard.
I don't think you will find this type of guitar with such a bizarre set of stats coming out of any factory, especially Fender. At the flattest, Fender will go with a 9.5" inch radius fretboard, and all pickups from Mexican to US to Indonesian will probably be suited to a midrange based flavor and not as treble based as EJ's preference. He also has a thin skin nitro finish which Fender never did. Fender would sometimes use nitro but never that thin and usually with poly, too. You can get a similar wind with Custom Shop Duncans but other than that, the EJ signature is totally unique and worth keeping, even if the average guitarist thinks it's just another Fender Strat.
If you can never find an EJ, you would have to go to someone like Warmoth, build a guitar with those parts, get Custom Fralins or Duncans to approximate the pickups, and then have a luthier spray a super thin nitro finish to get it all done just the way Eric has this strat and that will set you back $2,500 dollars, easy.
