In 1987 Irving patented a new design for classical
guitar tuning machines, to eliminate gear backlash. He designed the
machines to look better and work better than any others. Soon
afterwards he utilized his wealth of knowledge and redesigned these
patented machines for the string bass.
The central aspect of thepatent is the built-in
handle tensioning system. The system is a simple nut and washer
assembly at the base of the handle that not only allows for variable
"feel" while tuning but also for quick and inexpensive handle
replacement. But there is so much more to the Irving Sloane Bass
