Tech 21 Landmark 120
Tech 21 NYC Logo


This user-friendly, highly adaptable powerhouse is the EZ Pass to awesome bass tone in any situation. Styled after the acclaimed SansAmp Bass Driver DI pedal, the Landmark 120 boasts a simple control layout with active EQ, Presence to control definition and upper harmonic content, and Drive to push the amp into fat, formidable overdrive. A Blend control mixes your direct signal with the SansAmp signal for dense, detailed tone. The 120-watt output is easily handled by a custom-designed Eminence® 15” speaker, which uses a costly Neodymium magnet for high efficiency, ultra low weight and unbelievably fast attack. The buff Landmark 120 has the muscle for a stage rig and the finesse for studio tracking, courtesy of the proprietary SansAmp technology.

Distortion and Overdrive?
Pro-league bass distortion is not something you would expect from an affordable, compact bass combo, but we like to be the exception to the rule here at Tech 21. Our SansAmp technology delivers Richter measured rumble without outboard effects, overblown rigs, or even high volume.
