The 621 is a 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 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-lapping is a time-consuming finishing process which results in superior valve fit for noiseless, responsive action and easy tone changes.
