SFZ™ SERIES SNARE DRUMS
Renowned for its distinctive sound, wide dynamic range, and explosive rim shot, the SFZ (Sforzando) marching snare drum incorporates structural innovations that permit the use of a high-tension Kevlar® drumhead. Years in the making, the SFZ was developed and perfected in field tests under the rigors of actual use with The Cadets, The Cavaliers and The Madison Scouts drum and bugle corps. The design offers powerful projection, precise articulation and durable performance.
Snare Assembly
For urgent drumhead changes, the strainer system allows for quick and easy removal of the snare assembly. With the use of FiberTech™ snares, a crisp and articulate sound is obtained while ten independently adjustable strands allow for precise tuning control. The butt-side strainer uses aluminum die-cast construction for strength without excess weight, and has vertical adjustment capability for a precise setting of snare height. This also houses the independent adjustment for each FiberTech™ snaregut. The release-side strainer uses parts made of die-cast aluminum and durable nylon for a smooth, noise-free operation. An oversized vertical adjustment knob allows adjustment to snare height even when snares are engaged. For a precise setting of the snare tension, the horizontal adjustment knob is within easy reach of the player.
Suspension Ring
With the thickest wall in the industry, the SFZ suspension ring allows high-tension tuning without warping. It uses a solid, die-cast design and a special aluminum alloy to provide exceptional strength with minimum weight. It is also tall enough to accommodate the stretch of a plastic head. An extra long lug nut provides sufficient threading to effectively grip the tension rod. Its beveled edge guides the rod to eliminate cross threading, a feature especially helpful during last-minute head changes.
Shell and Lugs
The 6-ply birch shell built using Yamaha³ patented Air-Seal System® promotes a sharp attack with a full-bodied sound. Three air holes vent the shell to promote immediate snare response and to enhance projection. Tubular lugs are made of high-quality, lightweight aluminum, and feature a thick wall to resist dents and bending from heavy use.
Stabilizer Power Posts™
These posts support the tube lugs by adding considerable resistance against damage from accidental bumps and stick hits. Since they are secured to the shell, the posts help focus the drum³ tone and therefore, make the sound more articulate. To facilitate quick bottom head changes, the posts maintain the exact alignment necessary for the bottom tension rods.
Rims and Tension Rods
For consistent tuning and explosive rim shots, the top and bottom rims use a special aluminum alloy in a solid, die-cast design without excess weight. The 6mm diameter of the tension rods provides the extra strength necessary to maintain structural integrity under aggressive tuning conditions. Double steel washers allow smooth tuning adjustments at any tension.
Gravity Guards™
Locking nylon nuts help maintain tuning settings when set against the bottom rim. These act as lock washers to slow the turning of the rods caused by vibrations during play
Protective Feet
Exclusive to Yamaha, three removable feet eliminate damage to the bottom components of the drum when placed on rough surfaces
