Classic Maple's standard 7-ply, 6mm shell is formulated for optimum resonance and tonality. Its center three-ply core panel (laminated in a horizontal/vertical/horizontal grain bond to a 2.4mm thickness,) is inserted between inner and outer two-ply panels through our proprietary RFST molding process.

To increase stability through out the drum, all Ludwig USA shells are produced using Radio Frequency Shell Technology. Using a process involving our original bladder molds, R.F.S.T.'s unique bonding system -combined with a specialized, time-tested adhesive- cures each shell evenly over the entire surface of the shell. This process is truly a principal ingredient in creating the "Ludwig Sound" in every shell we make.
