Designed
by Sally Van Meter and Rick Shubb, the SP3 was created to be the
ultimate bar for playing bluegrass. Shubb has been paying attention to
what bluegrass players have been saying when they talk about bars.
Sally, one of the very best herself, suggested this design. She told
them "You ought to make one just like this...", and began to describe in
minute detail exactly how the bar should be.
