Cymbals and hardware not included. strongAir Seal System/strongBRAll Yamaha wood drums have one thing in common--Yamahas craftsmen create every drum shell using their exclusive staggered diagonal seam, Air Seal System just as they have since 1967. Each two or three-ply master ply is cut to length to very precise tolerance with a diagonal cut on each end. The diagonal seam in the drum shell will not separate, eliminating the need to fill gaps in the bearing edge with filler putty. These plies have glue applied and are then put into the mold by hand, one master play at a time. The craftsman then inserts an air bag into the mold and inflates it, clamping the shell with even pressure 360 degrees around. This process creates a drumshell that is strong, starts round, and stays round for many years.strong100% Maple Shell/strongBRTour Custom drum shells are 100% maple. The bass drums are 7-ply 7mm and have a warm, deep tone the toms are 6-ply 6mm, with lots of warmth and resonance and have a wide tuning range. The matching wood snare drum has body, yet plenty of high end and is very articulate at all dynamic levels.strong60 Degree Bearing Edges/strongBRAll Tour Custom drums have 60-degree R2 bearing edges. This is something new for Yamaha on a maple shell drum set. This bearing edge has a rounder profile so that there is more shell to head contact. This gives the drums clarity in the low-end fundamental and added warmth.strongBass Drum Spurs/strongBRSturdy, yet simple in design the bass drum spurs hold the bass drum firmly in place even under heavy playing. They are height adjustable using a drum key, and there are steel spikes that can be exposed when extra hold is needed. They fold up compact for transport and are marked with angle indicators so that you can set them up the same every time.strongYESS Tom and Floor Tom Brackets/strongBRAll Tour Custom toms and floor toms use the YESS (Yamaha Enhanced Sustain System). The toms have a mount attached to the shell at the nodal point by two bolts. This system allows the drum shell to vibrate freely for maximum sustain without restricting with where the placement of the drums. The floor tom brackets are small, minimal contact mounts that are located at the nodal point. They hold the legs securely in place without restricting the vibration of the shell.strongBall Clamp and Triple Tom Holder/strongBRTour Custom drum sets include the TH-945 triple tom holder with Yamahas tom ball clamp that gives you 360-degree rotation. The ball, made of a super-hard resin, is held in place by a single bolt making angle adjustments on the toms quick and easy. The toms lock firmly in place at virtually any angle you want. This versatile tom holder lets you mount any combination of up to three toms and/or cymbals by using either the standard or the long version of Yamahas tom ball clamp and CH model cymbal booms.strongBeautiful Lacquer Finishes/strongBRTour Custom drums are all finished in high-gloss lacquer.Cymbals and hardware not included.
