The Pioneer of Analog Amp Emulation
In 1989, performing musician and electronics technician B. Andrew Barta founded Tech 21 in Midtown Manhattan, New York, introducing a ground-breaking innovation to the music industry: the original SansAmp® tube amplifier emulator.
Combining extensive real-world stage experience with rigorous audio engineering expertise, Andrew sought a solution for musicians who demanded monster tube-amp tones without carrying heavy speaker cabinets or depending on microphoned amplifiers in unpredictable studio and stage environments.
Initially, major traditional gear manufacturers overlooked the revolutionary potential of direct analog tone shaping. Driven by conviction and technical mastery, Tech 21 USA established its independent production line in New York — creating an entirely new product category that forever redefined direct recording and global audio performance.
