pistons are resistant to corrosion and are an ideal choice for professional trumpet pistons which must retain precise fit and smooth action over many years. Hand hammered one piece bellA one piece bell has an axial lengthwise seam, making it a continuous extension of the instruments material. This results in pure, uniform resonance and superior tone. A hammered yellow brass bell produces a perfectly balanced tone with quick response and extra presence due to advanced manufacturing. Annealed bellYamaha employs special computer controlled annealing equipment to ensure that the end result of this heating and cooling process is a consistently superior sound. Hand lapped pistons and slidesHand lapping pistons and slides ensures an absolutely perfect fit and seal between the pistons and casing or slide parts. Such a perfect fit helps to achieve smooth air flow and smooth action and improve the response and intonation of the instrument. Pressure formed tubingPerfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance. Laser fused pluzuma welded bellA high energy laser fuses the brass together for a virtually seamless bell which allows continuous even vibrations. One piece drawn leadpipeThis type of leadpipe offers excellent intonation, response and proper resistance. Single main tuning slide braceThe main tuning slide on the YTR 8335RGS has a single brace which helps the response an
