The top one is actually extremely similar to Greco MX600, the volume/tone knobs and switches are clearly in the same position.
I am not thinking Greco anymore because it doesn't have the smooth carved Greco neck joint common to even the low end MX and MR models... so I think its more likely an Ibanez made to very similar spec at the same factory. I haven't picked up a low end Ibanez Artist in a while, but I wanna say they might have that bulkier neck joint and heel than the top shelf Artists and the Greco guitars like mine.
It could also be a low end Yamaha SG too. Even the High end SGs and Super Flighters have kinda bulky neck joints and heels. They are great guitars and all, but the similar Greco and Ibanez guitars got really long neck tenons (mine goes right to the end of the neck pickup route and possibly beyond, though I suspect it stops flush with the end of the route - also, if anyone tell you it doesn't make a big difference to the sustain they are fulla shit, that guitar resonates better than any other guitar I own) and so old grecos and iabnezes remain stable even with the surrounding body wood sanded flush in the cutaways and at the heel. I'm not sure the medium tenon Yamis and super short, SG butt joint style cheapies from Yami and 'Nez woulda survived this long if they had a more elegant carve around that joint.
Body looks small for an Yamaha SG though and the horns aren't devilish from what I can see in this shot. I'm not sure if Yamaha or Ibanez ever copied the Greco MX series' 3 knob + switch control layout either. I've seen Super Flighters with this screwball control layout, but never an SG with anything but the Gibson layout.
it might also be an epiphone, there are some rare 80s and 90s epis with this design, they evolved into the Gibson Tak Matsumoto (?) signature I think
if you guys can get more pics I'll ID this sucker, these are my favorite type of guitar, I like the higher end ones with the nice appointments and electronics, but I generally love all the MRs, MXs, Artists, Yami SGs, Gibson LP Studio DCs and even the Japanese Epi doublecuts... I am sure even without a headstock shot I can ID this thing... any time I see a guitar in this style I have to play it
