Eich Amplification is a German bass amplifier manufacturer based in Herborn, Germany, founded and run by Thomas Eich. The company grew out of custom loudspeaker work Thomas began in the mid-1980s, and has exhibited at Frankfurt Musikmesse since 1986 and the NAMM Show since 1992. In 2011 the company received a NAMM Association Milestone Award marking 25 years in business.

The brand specializes in bass amplification, producing bass amplifier heads (including the T-series such as the T1000, T900, T500, and T300, alongside Classic and Pride variants), combo amps (BC112, BC212, BC210, BC115), and a wide range of bass cabinets from compact formats to larger stage rigs. Eich also offers guitar amplification, replacement speakers, drum thrones, and accessories.

Eich has built a niche reputation among professional bassists for lightweight, high-power Class-D amplifier heads paired with neodymium-loaded cabinets, and the company is known for voicing its gear around transparent, full-range bass reproduction rather than heavy coloration.

Eich has 8 products cataloged on Equipboard, including Bass Amplifier Cabinets, Bass Amplifier Heads, and Bass Combo Amplifiers. Their gear is featured by 2 artists, with the strongest followings in Funk / Soul and Rock. Notable users include Nicole Row and Ida Kristine Nielsen.
