AmpForge vs Rustortion

AmpForge is a free, open-source guitar amp simulator plugin that also includes vocal effects. Its pedalboard has 19 internal modules that can be reordered while the plugin is running. The NAM module loads Neural Amp Modeler capture files supplied by the user. Vocal tools include autotune pitch correction and a de-esser for sibilance. AmpForge is available as VST3, LV2, and CLAP plugins, plus a standalone app on supported platforms. It can run in compatible hosts such as Reaper, Carla, and Bitwig. Users can save, update, delete, import, and export custom presets, alongside the included factory presets. Hosts can automate every parameter, including pedal positions. An IR loader is included, but users need to provide cabinet impulse responses and NAM captures. AmpForge supports Linux, macOS, and Windows. The Windows installer offers VST3, CLAP, and LV2, but no standalone executable. The macOS build is not signed or notarized; the README describes a Gatekeeper workaround for installation.

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.
