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.
Clean, Crunch, and Dual Tone
The Blues Cube has two independent channels—one voiced for cleaner tones, and
the other for crunch. Each channel has its own Boost and Tone switches to shape the
character. The Clean channel's single volume control dials in natural tube fullness and
bite as the volume is cranked, while the Crunch channel's variable gain control provides
a range of grit flavors from mild to aggressive. With the press of a switch, the unique Dual
Tone mode lets you blend both channels together for an endless array of rich tones. And
just like a vintage tube amp, the Blues Cube loves stompboxes, allowing you to further
shape your personal sound by hitting the amp's front end with your favorite gain pedals.
