This is a piston button for Bach trumpets made from pure titanium.
 Set of 3.
 It responds very well to low volumes and is very easy to control the volume.
 The sound contours become clearer.
 Even in large formations, it gives the impression of flying far away without getting lost in the crowd.
 The performance and tone of the trumpet itself remains the same, but the operability is improved.
 It would also be great for big bands, marching, piccolo trumpet, etc.
 It looks almost the same as the original, so feel free to try it out.
 These are newly produced custom parts made exclusively by UPMAKE.
 Please try it.
