If you're looking for that massive Thunderbolt tone with the added sonic splendor of a gorgeous, lush tube-driven reverb, the Supro 1675RT Rhythm Master 1x15 combo is the answer! Made in the image of the coveted classic Supro amp, this 1675T Rhythm Master sports independent treble and bass controls, an output tube tremolo, a six-spring long pan reverb and switchable Class A/Class AB power amp wiring for 35, 45 or 60 watts of pure, unadulterated vintage American tube tone.

The Supro Rhythm Master is powered by a pair of 6L6 power tubes, and comes loaded up with a single American-made custom 15" speaker that was designed in collaboration with Eminence. Giving you the best of both old-school and contemporary worlds, this speaker takes the best aspects of two legendary vintage speakers (Jensen C15PS & JBL D130) and pairs that with modern materials and construction to give you that sought-after vintage sound with unparalleled power handling and a thick, juicy low end. This accurate, true-sounding 15" speaker is never muddy, and sounds incredible in all frequencies.

Not only does the unique topology give you the ability to alter the texture and output volume of the amp, but it also allows you to achieve two very distinctive all-tube tremolo effects depending on whether the amp is in Class A (cathode bias) mode or Class AB (grid bias) mode. Switch to the cathode bias mode to dish out that legendary vintage Valco/Supro-style trem tone, where the effect changes with your playing dynamics. In grid bias tremolo mode, you get a strong, more pronounced throbbing trem effect with amazing depth. Since the tremolo is performed by modulating the bias of the output tubes, the all-tube reverb comes before the tremolo, which produces a beautiful blend of pure tube reverb and tremolo when both effects are combined. The Supro 1675T Rhythm Master is assembled in the USA, and features a Blue Rhino Hide tolex covering.
