hi
i once had a chambered body super real ,,,
dont know if it was a eg450 or eg500 ...i think it was from 1982
not a good guitar ,,,,, heavy even with the chambered body ,,,
came in some kind of tobbaco burst ,, with u 1000 i think
not the best greco i have had ,,, looked like some thing that was made just before weekend in a hurry
sold it long time ago
all the best
otto
