Hi Ahaja, looks like an interesting find.... a few questions (you might not know, but maybe ask the seller?)
Is it a through neck? (or thru neck if you prefer!)
Active or passive pickups? (i.e. does it need a battery?)
Is there a pickup selector switch? (can't see one, but could be part of one of the knobs)
Are there any serial numbers or makers marks at all? Possibly on the back of the head?
It's got a 1980s/90s Ibanez look to it with the light wood laminations, but I suspect it was probably just home-made from parts by an amateur. That doesn't make it a bad guitar, it depends on the quality of the parts! This was a popular thing to do in the 80's, when necks, bodies, pickups etc were easy to buy as parts and you just bolt them all together and do some simple wiring.
Incidentally, the reason under-scratchplate pickups are unusual is that it puts them a long way from the strings - it could suffer from low output and/or mains hum/interference, unless the pickups were well chosen or specially made.
fwiw, if it's cheap I'd just but it and try it out!! You can always sell it again if it's no good.
If you do buy it, post some more detailed photos and details here and we'll try to find out more about it.
