I've been experimenting with some new backbore designs to add to our ACB line. Right now I'm offering them at an introductory price, in raw brass (we can silver plate at an additional charge, just send us an email). There are three new sizes available, and they're all a bit different from our current offerings. The brass has a higher copper content and the interior dimensions are different from any of our current production backbores. The sound shapes with these backbores are a little richer and thicker.
Basic comparison info:
- Small: Somewhere between a Bach 76-85, a tighter commercial style design
- Medium: Similar to a Bach 10, a more all-around design
- Large: Similar to a Bach 24, orchestral style design
All come standard with a 27 throat (can be opened on request). These have the same "Warburton" threads as the rest of our two-piece mouthpiece parts, and they're compatible with tops from many other makers as well.
If you have additional questions send us an email.
