AmpForge is a free, open-source guitar amp simulator plugin for Linux, macOS, and Windows, with vocal effects and an IR loader. Its pedalboard contains 19 modules that can be rearranged while the plugin is running. For amp modeling, its NAM module loads Neural Amp Modeler capture files that users provide. Vocal tools include pitch correction with autotune and a de-esser for sibilance. AmpForge comes as VST3, LV2, and CLAP plugins, and as a standalone app on supported platforms. Compatible hosts named in its README include Reaper, Carla, and Bitwig. Users can work with factory presets or save, revise, remove, import, and export custom ones. Hosts can automate every parameter, including pedal positions. AmpForge does not include cabinet impulse responses or NAM captures, so users need to supply those files. On Windows, the installer offers VST3, CLAP, and LV2 formats but no standalone executable. The macOS build is neither code-signed nor notarized; the README provides a Gatekeeper workaround. The project welcomes issues and pull requests through GitHub.
