OK - Just thought I'd share!
They are, top to bottom, left to right:
"Tie Dye" - Pamelina artwork. 1989 serial #, but probably released as a late '90 or 1991 model. Low production graphic. Square neck heel.
"Surprise" UCGR1 - Pamelina artwork. 1989 serial #, but again, released in 1990 or 1991. Square neck heel.
"Leather & Metal" UCGR4 - Pamelina artwork. 1991 serial #. AANJ.
"Green Eyed Beauty" - A one-of-a-kind Pamelina prototype for Ibanez. According to Pamelina, anyway, this is the only one. Dated 1989. Square neck heel. A Christmas present from my wife.
"Gray Snake" UCMD1GS - Metaldesign series. 1989 serial #, but a '91 model. Square neck heel.
"No Bones About It" 92UCGR2 - Dan Lawrence artwork. 1991 serial. AANJ.
"Chopper" - Artwork by Klemann - 1989 serial #, but painted in 1990. Square neck heel.
Original USAC by Mike Lipe back when he worked for Ibanez. According to him, it's the only USAC he did with this paint job. I've seen at least one other Ibanez with a similar paint job (an earlier , non-RG model), but Lipe says this was the only "factory" USA Custom to get it. Maple neck, of course, with square neck heel.
USRG30TP - 1995 model. My wife gave me this one for our 10th anniversary. She's so cool!
"Serpent" UCMD1ST - Metaldesign series. 1990 serial #. Square neck heel. Note the 3-coil IBZUSAF3 bridge pickup!
That's it. For now.
Interesting how many have 1989 serial #'s but didn't show up in the catalogs until the 1991 model year.
If you can't tell, I'm addicted to USAC's. If anybody wants to talk customs, bring it on! Also, if I screwed up any of the specs I listed, please say so.
