About Metropoulos

George Metropoulos has spent years pursuing classic plexi tone - on the road, in the studio, in the workshop and online. He has become an authority on many things related to vintage Marshall amps and vintage plexi tones. His obsession has manifested itself in the Metropoulos replica amps and, more recently, the Metro-Plex and Super-Plex amps. Metropoulos Amplification has ushered in a new era of modern amp designs with authentic plexi era tones.

For many years, Metroamp, a division of Metropoulos Amplification, was THE source for all the parts needed to build a DIY plexi style amp, upgrade a reissue Marshall or restore a vintage piece. Now, Metropoulos has consolidated its divisions and offers its premium amplifiers, accessories (including the best-in-the-industry Zero Loss FX Loop) and parts all under one roof. Additionally the Metropoulos forum (forum.metropoulos.net) serves as a central archive for all manner of technical info and historical data. Its a lively community of amp techs, DIY-ers and amp nuts.

With the 2023 release of the Metro-Plex MK II, George has achieved the ultimate goal: separating cranked plexi tone from sheer volume.  This design may come to be his career-defining accomplishment.
