Friedman’s popular Dirty Shirley Head was designed for guitarists that wanted a Vintage Classic Rock tone inspired by British tube amps from the '60’s and '70s. And what’s better than one Dirty Shirley? Two Dirty Shirleys, aka the Twin Sister. The Twin Sister is a 40-watt, 5881 powered, dual channel head based on a modified JTM 45 but still delivers the signature British tone for which Friedman has become known for.

The amp features two identical channels that can give you everything from gorgeous sparkling cleans to a glorious vintage crunch and beyond. Extremely versatile, the Twin Sister can produce many styles of music from blues to rock and country by just adjusting the structure, gain and master controls. The Twin Sister features all the beautiful finishing and solid construction that you would expect from a Friedman amplifier. Designed to take pedals and loves boosts, ODs phasers, flangers, tremolos and wahs, while the ultratransparent series effects loop handles your time-based effects pedals and rack units.
