UltraSound Amplifiers is proud to be a Dean Markley owned company.

Early in 1998, UltraSound produced its first acoustic amplifier. UltraSound saw a need in the acoustic amplification market—for an acoustic amplifier that would replicate the exact tone of the guitar and other acoustic instruments. Through thousands of hours of fine tuning circuitry and testing and designing hundreds of different speaker configurations and sizes, the marvelous transparent acoustic tone that UltraSound Amplifiers are known for was achieved.

As of November 1st, 2007, Dean Markley, a pioneer in the music industry, acquired UltraSound Amplifiers.
