I own an Aeolian upright (46") that was made, I believe, in Korea, during the period that Peter Perez owned the company. It's really not too bad.
What I'd like to know is who exactly was making these pianos, Young Chang, Samick or who else ? Does it have a 3-ply type soundboard ?
Do any of the forum members, esp. techs, have experience with this type of piano and, if so, what is your impression ?

Thanks
