Spec score 7.2 #19 of 35 in Guitar Amp Software

What it is

Rustortion is a free guitar and bass amp simulator written in Rust for Linux and Windows. It runs standalone with JACK or inside a DAW as a VST3 or CLAP plugin. The processing chain has 12 DSP stages, including preamp, compressor, tone stack, power amp, effects, graphic EQ, and NAM model loading. Oversampling can be set from 1x through 16x, and impulse-response cabinet simulation is available for guitar and bass. Users can save and load presets, switch them with keyboard hotkeys, record in real time, tune, shift pitch with FFT processing, and use MIDI controllers. Plugin bundles are listed for Linux x86_64, Linux aarch64, and Windows x86_64. The project is MIT-licensed, experimental, and under active development, with use at the user’s own risk. Linux requires PipeWire, JACK support, and a Rust toolchain. There is no macOS build. The interface supports English and Simplified Chinese.
