Friedman Dirty Shirley Combo Guitar Amp

Dave Friedman’s Dirty Shirley open-back 1×12” combo was designed for guitarists that want a Vintage Classic Rock tone inspired by British tube amps from the 60’s and 70’s.

It is based on a modified JTM 45 but still delivers the signature high gain tone for which Friedman is best known. The Dirty Shirley is a 40-watt, 6L6 powered, single channel amp that will give you that vintage crunch and also clean up nicely by merely backing off the guitar’s volume knob. Extremely versatile, it is capable of producing many styles of music from blues to rock and country by just adjusting the gain and master controls.
