Sollo Amps is a Brazilian boutique tube amplifier manufacturer based in Brasília, founded by electrical engineers Filipe Carneiro and Renato Gomes, both graduates of the University of Brasília (UnB). The company specializes in compact, all-tube guitar amplifiers built around traditional Class A topologies and hand-wired construction.

The core product line centers on the Mini series of low- to mid-wattage heads and combos, including the Mini8, Mini20, and Mini50. The larger Mini20 and Mini50 models add features such as a clean-channel EQ, line output, switchable power reduction, and a volume boost, packaged into smaller-than-typical chassis aimed at players who want studio- and stage-friendly tube tone without the size of traditional rigs.

Sollo's profile sits within the wider scene of Brazilian boutique amp builders, and the brand has been covered in regional guitar press and gear blogs covering the country's homegrown amplifier makers.

Sollo has 3 products cataloged on Equipboard, including Guitar Amplifier Heads and Guitar Amplifier Cabinets. Their gear is featured by 1 artist, with the strongest followings in Rock and Metal. Notable users include Marcelo Barbosa.
