jAmp 8100 delivers an authentic digital emulation of the iconic Marshall Valvestate 8100 amplifier, renowned for its distinctive sound that defined numerous metal albums throughout the 1990s. This amplifier model was prominently featured by influential bands like Death, Prong, and Static-X, making jAmp 8100 a powerful tool for musicians seeking that classic aggressive tone. It functions both as a standalone app and as an AUv3 plugin, compatible with popular DAWs including GarageBand and Logic Pro, allowing seamless integration into various production workflows.

The plugin offers a comprehensive suite of built-in effects to shape your guitar tone, including a noise gate, compressor, and an emulation of the Ibanez Tube Screamer pedal. It also features a pre-amp chorus and a five-band post-amp equalizer, complemented by a stereo chorus effect after the amp simulation. An impulse response loader expands tonal possibilities with integrated IRs from forward-audio.com and Valhallir.at, while MIDI controller support with MIDI learn enables intuitive real-time control. These features provide a rich palette to craft solid-state distortion and dynamic textures.

jAmp 8100’s free version allows full access to all functions, with a brief silence every minute to encourage upgrade. A one-time in-app purchase removes this limitation. To use the app with a guitar or other instruments, an audio interface is recommended for optimal sound quality, with popular options including Focusrite and iRig. However, the AUv3 plugin can also be applied to prerecorded guitar tracks within a DAW, offering flexibility for producers and musicians who want to enhance existing recordings with authentic valvestate tone and effects.
