About Your New Blues Cube Hot
Wide-Open Sound at Any Volume (Power Control)
Every tube-amp player knows that you really need to turn up the volume and push the
output tubes to get the amp to sing at its best. The downside is that the sound simply
becomes too loud for playing anywhere but the biggest stages—though that’s certainly
never stopped guitarists from trying! The power amp section of the Blues Cube uses a
high-impedance drive circuit to drive the speaker in an authentic way. Even within the
power amp section, the bias circuit for each component such as NFB, phase inverter,
output transformer network, and power supply uses an independent circuit structure and
is tuned independently.
With Tube Logic, the Blues Cube authentically delivers the complex distortion
characteristics of output tubes and their interaction with the output transformer, with
the sound getting richer and the feel becoming more dynamically responsive as the
overall volume is increased. But with the Blues Cube’s variable Power Control, you’re able
to enjoy this musical, cranked-up tone while matching the volume to any situation, from
recording to rehearsals to nightclub gigs and beyond.
