I've had a 7 pc. set of yamaha oak customs for quite some time now. I've never had a problem tuning drums, or getting drums to sound good to my ear, but these things are so ringy they are driving me nuts. I've tried loose tuning with aquarian heads. I've tried muffl rings, and many other tricks. If anyone else here uses oak customs, and has them sounding good i'd love to know how they did it.
