Whether you're looking for a clear, ringing alto sound for concerto performances, or a sound that's more along the lines of a traditional German alto trombone or if you prefer a mixture of clarity with warmth to cover the widest spread of alto repertoire, then the R11 can be customised to cover all eventualities.
What is common for everyone, though, is the need for an alto that not only sounds like an alto rather than a tenor trombone but, equally importantly, is easy to play, is in tune with itself and does not require much adjustment by the player when switching from tenor trombone - in short playability. The R11 achieves these goals perfectly.
The R11's slide has a comfortable seventh position for E and A and enough length to allow fine tuning of both of these. The slide tuning system means that the relative harmonics of the R11 are where you'd expect them to be and the relationship between harmonics does not change as you adjust the tuning which can be the case with many alto trombones with tuning in the bell section.
Like all Rath trombones, the R11's slide action is superb and the small additional weight of the slide tuning system won't slow you down, even on the most technical of passages.
There are two bore sizes for the R11 - the R11Z (0.481"/0.491") and the R11K (0.481"/0.500") and any of our usual options for bell, slide and bell crook materials and finishes can be specified. The standard bell flare size of the R11 is 6 3/4", but a 7" flare is available on request.
Two sets of interchagable leadpipes, the "Z" and "K" series, have been designed specifically for each bore size and can be ordered in brass, nickel, silver and also in bronze.
Rath alto trombones are also available with a standard rotor in Eb/D or Eb/Bb.
We have a large stock of these instruments, each of which is customizable so please contact for current price, availability and shipping.
