Re: the schiller American Heritage 6 Valve Rotary F Tuba
As far as I can tell, changes/improvements are implemented by the factory as requested by dealers. JinBao seem quite open to implementing as requested and are about to do so to another model for Wessex Tubas as I will announce once I have a successful prototype in my hands.Lingon wrote:And they are not improving on the original construction over time in the ongoning production, in the way modelerdc suggested?Neptune wrote:...I am informed by JInBao that they only manufacture one model of the JBFB-600, so if there is an improved version, those improvements must be made post production...
If anyone can work out what changes are needed to the F tuba to make it play in tune (and modify one as an example to prove), I will happily take to the factory on my next visit to request incorporation in production.
My perception (and it is only perception) is that the expansion after the valves is just too fast and doubt if changing leadpipe is the solution.
