With focus on a refined shell construction, this new era of Neusonic boasts Rapid Tom sizes and captivating new finishes. The 5.5mm, 7-ply crossover shell design is formed at Ludwig's Monroe, USA factory from a 4-ply  Maple exterior and 3-ply Cherry interior - a design that delivers full-bodied tone and unmatched sustain. Shell Expertly crafted in the USA, Neusonic shells feature a 7-ply, 5.5mm design constructed with a 4-ply Maple exterior and a 3-ply Cherry interior to deliver outstanding power, resonance, and sustain. Bearing Edge Thanks to the single 45° bearing edge and ¹/16 back cut, Neusonic shells boast a broad tuning range and unmatched sustain. RFST Molding For greater stability throughout the shell, all Ludwig USA shells are constructed using Radio Frequency Shell Technology. RFST's unique bonding method, combined with a proprietary, time-tested adhesive is a process that uses Ludwig's historic bladder molds from the late-'60s to cure each shell evenly across it's entire surface. This construction method is a crucial element in delivering the classic Ludwig Sound in every shell they make.
