Landmark 300
Two differently formatted channels deliver everything from warm classic tube tones to Sumo-sized distortion. This 2U, 300-watt rackmountable head features a fan-cooled chassis and is equally at home in a rack system or as a compact stand-alone head. Its heavy gauge steel case is touring tough. With pro features like a +10dB gain switch to enhance low output pickups and drive active pickups harder, and aSansAmp XLR Direct Output, this amp will quake the bedrock live and in the studio.

SansAmp XLR Output works like a built-in direct box to deliver the true tone of the amp to the PA desk or studio board without compromising detail, warmth or responsiveness. The XLR is switchable from -20dB to 0dB.
Gain is a 10dB gain boost to set up the pre-amp for different pickups. For example, with lower output, passive pickups, you can have punchier sounds with Gain engaged. Conversely, with higher output, active pickups, you can have a cleaner sound with Gain disengaged.
