This is the 5/4 size solo rotary F tuba, and stands out from the crowd as one of the very best rotary F tubas with a centered low C and an even all-around low range. Available in yellow or gold brass, with 5-6 valves in several configurations. This is a more compact sounding instrument than the 181, but with a more centered low range. .772"-.835" conical bore, 15.75" bell
We've ordered these in 5 valve, all right hand, in yellow brass, or the 6 valve version, 4+2 German style or 5+1 USA style, in all gold brass. I have seen mostly 5+1 6-valve F tubas, but after playing a German style 4+2, I see the ease of fingering low passages without having to engage the thumb. Especially for C to Bb to A, it's fingered 4, 4+5, 4+5+6 respectively, all very easy. Check it out.
Included: mouthpiece and lubricants, case sold separately
