Mean spirited, full range tube amp saturation with great sustain. This box is your classic, high gain, hot rodded, rock distortion work horse. The full range saturation tone is meaty and raw, but still alive. High harmonic content power chords resonate freely but the tonal integrity of the amp and guitar signatures stay intact. This is a very dynamic box, and the two position toggle effectively gives you two distinctly different tonal signatures. This box is pure rock-n-roll thump.
