other companies, and began manufacturing drums under their own name and used the Pearl logo for the first time. Their construction technique is known as SST or "Superior Shell Technology." All Pearl drums feature this construction. Each ply is placed into a cylinder, and pressure is applied from both sides. While in the press, the shell is heated to bring the glue to a boil, thus forcing it through the wood grain and fusing the shells very tightly. The individual plies are scarf jointed, and all the seams are offset, resulting in a "seamless" drum (Pearl demonstrates the strength by parking a Humvee with its tire on a tom shell). This creates a drum shell of incredible strength. Drum lines Beginner and semi-professional lines Midtown (MDT) - a compact 4-piece poplar drum kit which consists of a 16x14 bass drum, a 10x7 tom, a 13x12 floor tom, and a 13x5.5 snare. Roadshow (RS) - a 5-piece drum set with a 9-ply Poplar shell. This kit is made for beginners. A throne, a Dual Chain drive pedal, cymbals (16“ Crash-Ride Cymbal, 14" Hybrid Brass/Hi-Hats), Maple Drum Sticks (2 pr) and a Professional Stick Bag are also included. Export (EXX) - introduced at Winter NAMM 2013, the EXX is Pearl's reintroduction to the Export line in less than a decade. This is the best selling drum set of all time. Designed to replace the Forum series, these drums are made from Poplar and Asian Mahogany shells and feature Pearl's "Opti-Loc" suspension mounts. Export (EXL) - essentially the same as Export EXX but with a Lacquer finish. Decade Maple (DMP) - all maple drum kit with an affordable price tag. Pearl Decade Maple features a thin 6ply/5.4mm Maple Shell, an Opti-Loc mounting system and low mass/low contact hardware. Professional lines Crystal Beat (CRB) - seamless acrylic drum set reintroduced at Summer NAMM Show 2014. Originally the first Crystal Beat was launched in 1973 and featured 'Sonaglass' - Pearl's acrylic shell equivalent. Crystal Beat's revolutionary seamless construction was molded - not rolled - creating a strong acrylic drum system that could stand up to the rigors of touring. The updated version features several modern changes: Optimount suspension system, 1.6mm triple-flanged hoops and a new acrylic material. Session Studio Select (STS) – Introduced at Winter NAMM 2018, the Session Studio Select kit replaced the discontinued Session Studio Classic.
