Ok, I saw these Ibanez guitars in a 2nd hand store and need help on what exactly they are. They were both $529AUS. Hopefully someone can help me out here.

Both the guitars had 7 strings.

One of them had a body similar to a strat. It had 1 green bridge humbucker, and no other pickups.
It was grey and had a typical Ibanez headstock.

The other had a shape like this: http://img.epinions.com/images/opti/4d/91/instGuitarsAllIbanez_AX7221_7_String_Electric_Guitar_Gray_Pewter1-resized200.jpg

I think the pick-up setup was HSH, but I'm not exactly sure.

Any help would be appreciated.
