Does anyone know the rough equivalent of a Bach 57 backbore in terms of Warburton or Schilke or something else? I put one on my Patrick FR88S top, and it's magic, so I'm curious about the possible equivalencies. Thanks!

Been a while!
I believe it was intended for rotary trumpets, and not particularly large (the 87 is another rotary backbore and that one is huge).
Unfortunately it doesn't appear to be on the backbore comparator... If Venture have it on file and you ask nicely on the comparator thread it might be possible to get it added. |
