For those players who love the huge, bold sound of the 1 x 15” Thunderbolt amp, but need a lush, all-tube reverb to fill out their sound, Supro presents the 1675RT Rhythm Master amplifier. Rooted in Supro tradition, this vintage-inspired model is loaded with independent bass and treble controls, six-spring long-pan reverb, output-tube tremolo and switchable power. The Rhythm Master’s 35-Watt Class A (Cathode Bias) mode delivers a more spongy, vintage character while the 60-Watt Class AB (Grid Bias) mode delivers faster transient response with maximum available headroom and volume.
A modern rendition of the low-wattage Supro amplifiers that were produced in Chicago during the mid 1950s, plus a line out for direct recording.
Delivers the authentic 6V6-powered tube-amp tone of the Chicago-made Supro combos from the 1950s along with genuine analog spring reverb.
Captures the vintage Supro amp tone that helped sculpt the sound of early electric Rock & Roll and the British Invasion of the 1960s. A host of features and 15 watts of power.
Unobstructed, Class A all-tube goodness propelled by the Jensen P12Q speaker.
Featuring tube-driven spring reverb, independent gain and master volume controls, 2-band EQ and three tube-driven line-outputs.
Reissue of the iconic single knob 1x8 combo amp made by Supro in the early 60s. Because sometimes you only need one knob.
