A 50 watt, all-valve single channel amp with two 12 inch speakers, 4 ECC83 pre-amp valves and 2 KT66 power amp valves. With two footswitchable ‘dynamic ranges’ you can choose between classic vintage Marshall tones, or by adding an extra preamp valve, more hard rock tones of the seventies. With Body and Detail controls, as well as two ‘frequency selective’ gains, you can get a substantial fat and smooth tone that responds to the playing style of your guitar. These are a nice mix of vintage classic mid 60s to early 70s blues tones and more hot-rodded sounds from the harder acts of that era.
