The new Friedman Twin Sister all-tube amp is basically two Dirty Shirleys in a single amplifier. The amp is based on that classic ’60s-70s Marshall-style tone, and is available as both a head or a combo.

Friedman Twin Sister

Friedman Amplification’s latest offering, the Twin Sister, was first unveiled at Winter NAMM, and is now finally available to order. Like the Dirty Shirley, the amp is based on a modified Marshall JTM 45 circuit. However, this time, instead of a single channel, you get twice the pleasure, in this new twin-channel format. The Twin Sister is a 40 Watt tube amp with five 12AX7 valves in the preamp section and two 5881 valves for the power-amp side. The combo version comes loaded with a single 12-inch Celestion G12M Creamback speaker. The amp itself can be run run at either 4, 8, or 16 ohms output.

Double The Pleasure

Each of the Twin Sister’s channels has separate Master and Gain control, along with a three-band EQ with the standard Bass, Middle, and Treble controls. These are then complemented by global Presence and Deep controls, plus a three-position gain structure switch. So plenty of options to play with to adjust your tone to taste.

The amp has the famous Friedman ultra transparent series effects loop, which I’m a big fan of and think works very well. It’s great for adding a touch of delay/reverb to your amp setup, without compromising your tone.

Overall, I think this is a great looking amp and will satisfy a lot of players’ needs for a high quality, all-valve boutique Marshall-style tone.

RRP – Head USD 2799 Combo USD 2999
