The YFB-621S is ideal for soloists and those who need an optimum of control and tonal clarity. The response is quick and secure, and the intonation extremely accurate. And the warm, rich sound has a focused tone center for superior projection.



Monel pistons

Monel pistons are resistant to corrosion and are an ideal choice for professional baritone pistons which must retain precise fit and smooth action over many years.

Hand-lapped pistons

Hand-lapping is a time-consuming finishing process which results in superior valve fit for noiseless, responsive action and easy tone changes.

Hand-lapped slides

Hand-lapping achieves the perfect balance between airtightness and smooth action.

Full, well-centred sound

The tone of the 3/4 size F tuba makes it ideal for either solo or orchestral playing.
