Get the ultimate American Plexi guitar amp plugin

Jim Marshall originally designed the British tube Plexi heads, famously used by legendary guitarists like Jimi Hendrix and Eric Clapton. Dave Friedman, an American innovator, enhanced these designs with his expertise in modifying Marshall Plexis, leading to the creation of the BE-100 hardware. This hardware, celebrated by artists like Alice in Chains, Pink, Bon Jovi, Billy Idol, The Cult, and Foo Fighters, is renowned for its applications in classic rock, hard rock, metal, punk, country, and blues.

Choose from clean and pristine to harmonically rich tones

The Friedman BE-100 plugin is a powerhouse for guitarists seeking a spectrum of tones, from clean and pristine to harmonically rich. Its dual-channel setup, powered by EL34 tubes, offers a robust, tight low end, clear chord definition, and satisfying saturation. With the versatility to deliver punchy, dynamic Plexi tones and an inspiring clean channel equipped with comprehensive controls, this plugin enables you to achieve perfect tonal balance, from aggressive riffs to pristine highs, all with minimal EQ adjustments.
