What is the MicroLok™ Valve Guide System that is used on Sonaré trumpets?
The MicroLok™ valve system was co-invented by Cliff Blackburn and Steven Wasser and is used in all Sonaré trumpets. During the production process, a custom made tool sets the piston into its perfect radial and vertical alignment position. As set screw is then tightened to lock the adjustable valve guide and secure the Monel piston into place. While this adjustment is permanent, MicroLok™ allows the alignment to be reset at any time by a trained technician, without soldering. Valves can be cleaned and oiled without disturbing the alignment.
