From what I found out recently, the old ROC drums were an effort to bring a high quality of manufacturing to inexpensive Luan shells that had been coming out of SE Asia for years.
I guess the result was a pretty nice sounding drum that tuned up easily and exemplified all the classic traits of Luan, which is a really fat and warm sound.
I believe they were made in California and the guy who made them had been a wood worker for almost his whole life.
So if your old drums were actual "R.O.C." brand drums, there's nothing "cheap" about them.
These days, C&C has taken up that mantle, offering a couple of models of their drums utilizing Luan shells.
Reports are that those drums are pretty nice, too.
P.S. - Not an ROC kit, but one of mine...just to keep the thread on track....
