Louis Electric is a boutique guitar amplifier company based in Bergenfield, New Jersey, founded in 1992 by Louis Rosano. The company specializes in hand-wired, point-to-point tube amplifiers built in small numbers, with designs that draw on classic American and British circuits while adding Rosano's own voicings.

The lineup includes models such as the Buster, Baby Bluesbuster, Columbia Reverb, Deltone Reverb, Gattone, KR12, LE58 Twinmaster, Tremoverb, and the Cobra series (including the 6L6, KT-66/183, and 183 Head and Combo variants), along with the Bassmaster for bass players. Cabinets and heads are typically wrapped in tweed or covered tolex with vintage-style cloth grilles, reflecting the brand's roots-rock and blues orientation.
