Dave Friedman's Dirty Shirley open-back 1x12" combo was designed for guitarists that want a Vintage Classic Rock tone inspired by British tube amps from the '60s and '70s. 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, 5881-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.

This handcrafted in the USA combo utilizes tongue-and-groove Baltic Birch construction and houses a 16 ohm, 12" Celestion G12M Creamback speaker that delivers the bass, mid response and signature sound you would expect from a Friedman amplifier.

The Dirty Shirley also features a three-position gain structure switch which lowers the overall gain of the amplifier.

The Dirty Shirley 1x12 combo was designed to take pedals and loves boosts, ODs, phasers, flangers, tremolos and wahs, while the ultra-transparent series effects loop handles your time-based effects pedals and rack units.

Hand-wired in the USA.
