I love my Jems and my UV, but you can get stuck in a rut with those things, they are great, but there are other guitars out there with different qualities that they cant match, so here's my list of others!
at present im proud to have in my possesion a:
60s Gibson Les Paul (makes me look like jimmy page!)
ESP-MIII Custom (it has the same mystic dream finish as a JS90th!!!)
Gibson Custom Shop Explorer (its a tone monster

)
Fender Yngwie Strat (needed those scallops!!)
a Yamaha nylon strung electro acoustic
and a Dean 12 string electro acoustic
(plus a random classical that ive had forever, sounds great, so its staying!)
They all get along nicely with my FP, BFP, VSBL and UV777!
its good to have a bit of variety
