Key Features
All tube, all blue, all tone. The Supro Rhythm Master 1x15 Combo w/ Reverb & Tremolo is a true sound machine. Sporting a massive 15" speaker that was meticulously designed with the people at Eminence to come up with the best speaker they possibly could, and the result is astonishing.
Set in class A mode (35W), the Rhythm Master is thick, spongy, and bold. This is the mode that has the least headroom, but it shows off what the Supro tone is all about - especially when the amp starts to break up. The Rhythm Master boasts a tone which will always come to life, no matter which genre you're playing.

15’’ speakers aren’t commonly associated with guitars - they tend to sound muddy with uncontrollable bass. The custom speaker by Eminence draws influence from the Jensen C15PS & JBL D130, which are great examples of a 15’’ speaker which gives exceptional bass and clear treble. This is a vintage-voiced driver with modern-day power handling.
This isn’t just a power rating but something that effects headroom, tone, and how the tremolo works. At 35W the amp is working in class A cathode bias. The amp breaks up much earlier so you can start hearing that 6L6 work, permeating the air with rich harmonics and lush touch sensitivity. This is great for a huge 'blues' tone. This also affects the tremolo. Set at cathode bias, the depth is affected by how dynamic your playing is. When you start running the Rhythm Master at 60W you will instantly notice the sound clean up, reacting razor fast to your playing, which sonically holds each note up to a microscope. This is a warm and stunning clean tone that would sit pretty in a Soul or RnB band.
The effect implementation is another thing that sets this amp apart. The all-tube reverb and tremolo sound superb. From a hazy morning beach vibe in cathode bias to an abrasive and intense helicopter-style tone when used in grid bias mode, youy can access a range of different voicings to make your music truly outstanding. Together, these two effects fuse making a pretty, otherworldly tone that transforms your guitar sound.
