Friedman Amplification has launched the Twin Sister, which puts two of its popular Dirty Shirleys into a single amplifier. The amp was designed for players seeking out a “vintage classic rock tone inspired by British tube amps from the 60s and 70s,” said Friedman.

The Twin Sister is a 40-watt tube amp and – like the Dirty Shirley – draws from a modified Marshall JTM 45. Each is handcrafted and comes as either a dual-channel combo or head.

The amp uses five 12AX7 valves in the preamp section and two 5881 valves to drive the power amp. With the combo variety, you get a 12-inch Celestion G12M Creamback speaker at 16 ohms.

Promising to deliver “gorgeous sparkling cleans to a glorious vintage crunch and beyond”, the Twin Sister boasts powerful yet familiar controls.

On each channel, you’ll find master and gain controls, as well as a three-band EQ with bass, middle and treble knobs. Adding to those are global presence and ‘deep’ knobs to further sculpt your tone with, and a three-position gain structure switch which lets you quickly alter the characteristics of the drive.

The Twin Sister also plays extra well with pedals and outboard gear, thanks to an Ultra transparent series effects loop located in the back. And for impedance matching, there’s a three-way impedance selector for running the amp at 4, 8 or 16 ohms.
