"And if you want to play around on a mouthpiece safari first, go for the Arnolds & Sons range, sometimes marketed as Stoelzel. They are reliable copies of Bach favourites at incredibly low prices..."
Better made than some Bachs in the '90s. Using these mouthpieces allow us to try all kinds of modifications cheaply. Throat sizes (drill bit and a vice) can be easily enlarged, as well as the backbore (fingernail files for reamers).
A fun project is to match the popping frequency of the backbore to the cup, filing off the end of the shank until they match--then machine a Morse taper to the appropriate end diameter.
Adds zing to the response.
