Rustortion
What Rustortion is
Rustortion is a free guitar and bass amp simulator written in Rust, available as a standalone application or as a plugin for a digital audio workstation. Standalone use runs with JACK; plugin formats are VST3 and CLAP. Its processing chain has 12 DSP stages, including preamp, compressor, tone stack, power amp, effects, graphic EQ, and NAM model loading. Oversampling is configurable from 1x to 16x, and impulse response cabinet simulation supports guitar and bass. Users can save and load presets, then switch between them with keyboard hotkeys. The feature set also includes real-time recording, a built-in tuner, FFT-based pitch shifting, and MIDI controller support. Builds are available for Linux and Windows, with plugin bundles listed for Linux x86_64, Linux aarch64, and Windows x86_64. Linux x86_64 is labeled as tested in a DAW; the other listed plugin builds were produced in CI but not hand-tested. The project is MIT-licensed, experimental, and under active development, and advises using it at the user's own risk. Linux builds require PipeWire and JACK support and a Rust toolchain. There is no macOS build.
Who it suits
Rustortion suits guitarists and bassists who want amp simulation either standalone with JACK or inside a DAW as a VST3 or CLAP plugin. It may also suit users looking for configurable processing, cabinet impulse responses, presets, and MIDI controller support on Linux or Windows.
What it does well
- Free and MIT-licensed, with standalone, VST3, and CLAP options.
- Twelve DSP stages include preamp, effects, graphic EQ, and NAM loading.
- Configurable oversampling ranges from 1x to 16x.
- Impulse response cabinet simulation supports guitar and bass.
- Includes tuner, real-time recording, pitch shifting, and MIDI support.
What to know first
- There is no macOS build.
- Linux requires PipeWire and JACK support plus a Rust toolchain.
- The project is experimental and advises use at the user's own risk.
- Linux aarch64 and Windows plugin builds are not hand-tested.
Limits
Rustortion has no macOS build. Linux use requires PipeWire and JACK support and a Rust toolchain; plugin builds for Linux aarch64 and Windows are built in CI but not hand-tested.

Getting started
- Open the Rustortion GitHub project page.
- Choose a Linux or Windows build that matches your system.
- For Linux, ensure PipeWire and JACK support and a Rust toolchain are available.
- Run it standalone with JACK or load its VST3 or CLAP plugin in a DAW.
- Save presets and switch between them with keyboard hotkeys.
Verdict
Pick Rustortion if you need a free amp simulator for Linux or Windows and want standalone or DAW plugin use with flexible processing. Look elsewhere if you need a macOS build or prefer software described as beyond experimental development.
