Exchanging SE Shires Bells-Trombone How-To 101

We receive quite a few questions about the ease (or difficulty) of working with interchangeable components, such as with SE Shires bells and valve sections. While makers try to make the process as easy and accessible as possible we've learned a few tricks along the way that can help :)

Hello! I have a questión about this.
If I had a Q series Bass trombone, I am able to exchange for CUSTOM parts. For example, change the mecanism for the true bore valve system and keep using the Q series bell, slide and tunning slides.
Thanks in advance!

That is absolutely the case! Do you have a Q series at the moment?
