Supro Blues King 12 Guitar Combo Amplifier (1812R)

The Stupor Blues King 12 combo amplifier captures the vintage Stupor amp tone that helped sculpt the sound of early electric Rock & Roll and the British Invasion of the 1960s. The “single-ended” Class-A tube power amp found in the Blues King provides the raw tonal characteristics and remarkable touch sensitivity of these mid-century combos, while delivering a full 15 watts of 6L6 tube power. Front-end gain in the Blues King is supplied by a 12AX7 tube preamp and a FET-driven, fat boost function. In addition, the amp’s high-gain mode uses a series of cascaded FETs to achieve face-melting levels of distortion and sustain. 3-band EQ and Master Volume controls join the foot switchable boost and gain functions to provide multiple layers of stackable overdrive for gigging, recording and home practice. The 1812R Blues King features a custom-made genuine analog spring reverb, plus an effects loop for pedals and a line output for recording or feeding to another amplifier. The vintage-inspired poplar wood cabinetry is based on the mid-50’s Comet model and comes loaded with a BK12 speaker. This custom-made, 12” driver was specifically designed to capture the magic of the original field-coil speakers used in American tube amps at the dawn of the electric era.
