Yamaha YTR 6345 GS

Monel pistons - Monel 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.

Hammered one-piece bell - A one-piece bell has an axial (lengthwise) seam, making it a continuous extension of the instrument's material. This results in pure, uniform resonance and superior tone. A hammered, gold brass bell produces a perfectly-balanced tone with quick response and extra presence due to advanced manufacturing techniques.

Hand-lapped pistons and slides - Hand-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 tubing - Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.

Laser-fused pluzuma welded bell - A high-energy laser fuses the brass together for a virtually seamless bell which allows continuous even vibrations.

One-piece, drawn, gold brass leadpipe - This type of leadpipe offers excellent intonation, response and proper resistance.

Conventional tuning slide - The main tuning slide on the YTR-6345G has a single brace which creates moderate resistance in the horn with a slightly darker sound.
