AMT (Asia Music Technology) was the brand name used by AMT Electronics from 1991 until 2001. The company has its origins in Russia in 1982 when Sergie Marichev began building effects pedals, and then eventually electronic drum kits, and even MIDI instruments. In 1987, when private enterprise was permitted in Russia, Marichev launched his Asia company. In 1991 it was renamed Asia Music Technology company (AMT) and it was renamed again in 2001 to AMT Electronics.

There is also an AMT classical guitar brand - made in Asia. It is unclear whether this is related to AMT Electronics or not.
