My son in Florida purchased a set of Remo Acousticon-220 drums off Kreggslist and I'm having a very hard time finding any info on them.They are 12/13/16/22 in standard depths,have a Yamaha-style to L-arm mount system(very solidly built)red PVC type covering,and some weird swing-out spurs.No Mastertouch or any other designation-just Remo and Quadura.Small lugs(not the triangly hollow ones) relatively close to the edges.I'm guessing 90's-2000's.Very dark interiors.I've heard some VERY good sounding Remo drums.3 days of searching and not much to show for it.
