Olsson Amps is a boutique amplifier company based in Hägersten, just outside Stockholm, Sweden, founded by Magnus Olsson. The company specializes in hand-built, hand-wired tube amplifiers and effects pedals produced in small numbers, with each unit assembled in Sweden rather than mass-manufactured.

The amplifier lineup includes the EL34-powered BJF100, the EL84-driven Little Hill 20, the Club Fifteen and Club Forty, the Stage 40 Nord, the Blues Fifteen, and a series of Custom Reverb models. On the pedal side, Olsson builds overdrives and fuzzes such as the Brownie, GreenLight, D.O.G Drive, The Wizard OD, The Spell Booster, and The Fuzztner — an octavia/fuzz developed in collaboration with Swedish session guitarist Staffan Astner. The company has also worked with Opeth guitarist Fredrik Åkesson on amp development.

The brand sits in the European boutique tube-amp scene alongside other small Scandinavian builders, with a focus on point-to-point construction, vintage-leaning circuit topologies, and signature collaborations with Swedish players. Distribution is primarily direct and through specialist dealers in Europe and North America.

Olsson has 3 products cataloged on Equipboard, including Guitar Amplifier Heads and Fuzz Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock and Metal. Notable users include Fredrik Åkesson and Magnus Olsson.
