Step up to the biggest and the baddest. Packing 300 watts of unfaltering SansAmp tone dare ye look directly into the eyes of the omnipotent Trademark 300 stack? Endowed with three fully independent channels in a traditional head format, our flagship model amplifier allows seamless switching between three of your favorite tones, from crystal clean to brutal crunch to searing lead. The active three-band EQ on each channel allows limitless tonal variations, putting you firmly in control of this beast. Available with a variety of cabinet options, the Trademark 300 is total tonal freedom with an arena-sized attitude.

The included high quality footswitch offers easy access to each channel, the Boost function, and individually engages each of the two Effects Loops.
