Trevor Byers worked at the Fender Custom Shop in Corona, CA for many years before he began building his own amplifiers in the 2000s. Byers' first amp was his original creation called the Model 10 and he followed that up with a recreation of one of Leo Fender's earliest K&F amps. Byers specialized in K&F amps and early Fender amps from the late 1940s. The price for a reproduction K&F Byers amp was around $1,000.
