Classic Class A design using 2 x EL84 output valves and 3 x ECC83 pre-amp valves. Special design tone network. Setting all tone controls fully anti-clockwise gives no output. Dial in exact tone you want. Like having three extra volume controls at different frequencies!! High and low sensitivity inputs. Gain and Master volume controls. No FX loops or DIs or other interuptions from your guitar to those sweet sustaining tubes. Giving you the creamiest, raunchiest controllable distortion on the planet. Use with our specially designed 2 x 12" speaker cabinet, or for that big sound, use with our 4 x 12". Powerful enough to drive both of them. 4, 8 and 16 ohm selector for matching to any cabinet. All Hiwatt point to point construction.
