Traditional "Germanic" sound perfect for certain types of orchestral literature. The FFM in the model number stands for Frankfurt am Main; developed at the Yamaha Frankfurt Atelier with input from Markus Bebek, Associate Principal Trumpet of the Opera Frankfurt am Main.

Features:

Leadpipe: The taper of the leadpipe on the rotary valve trumpet has the optimum taper for superb intonation and dark powerful tone.

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

Hand-lapped valves and slides: Hand-lapping rotary valves and slides ensures an absolutely perfect fit and seal between the valve 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.

Tone: Softer and rounder than piston valve trumpets.
