| Hi,
That's the wonder of the Warburton system!
You're now able to dial in the resistance and sound you want for specific gigs as well is super-fine tune the exact resistance and sound that works best for you.
Kanstul also now makes threaded backbores on the Warburton system and you can get different Bach backbores that have been digitized by Kanstul.
Altogether, a wonderful idea.
If you get a chance, try the new Warburton "O" backbore . . . a great lead backbore that has just come out!
