We always recommend JJ valves for this amplifier. This is because they guarantee you get awesome tone and long life and they don’t cost a fortune.

What Supro say about this amplifier.

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 analogue 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.
