Blackstar Amplification is a UK-based producer of guitar amplifiers and effects units, largely made up of ex-Marshall employees. In 2009 they began operations in the United States. They manufacture some units in the UK—but have most products made in Asia, some in Korea, but primarily in China.

Blackstar produces guitar pedals for boost, overdrive, distortion, distx, modulation, reverb, delay, dual and metal. Some of the pedals incorporate valves (tubes) in the electronics, the drive pedals incorporate Blackstars ISF feature. Like the HT-5, some of the pedals have an emulated speaker output for direct recording.
