AmpForge

AmpForge is a free, open-source amp-simulation plugin that combines a reorderable pedalboard with Neural Amp Modeler loading and a small set of vocal effects. It is best suited to guitarists and producers who want host-automated signal chains and are prepared to provide their own captures and cabinet files. The broad format support is a strength, while installation and sound-library setup require more effort than an all-in-one commercial package.

Overview

AmpForge puts guitar amplification, effects, and vocal processing in one project. Its central appeal is flexibility: the signal chain can be reshaped while running, and the same project can be used as a plugin or, on supported platforms, as a standalone application. Because the project is open source and accepts contributions through GitHub, technically inclined users can also engage with its development rather than treating it as a closed product.

Key features

The pedalboard contains 19 internal modules, with runtime reordering. That is useful when a song needs a different effect order or when a player wants to experiment without rebuilding a session. Every parameter is host-automatable, including pedal-position controls, so compatible hosts can place effect changes precisely in an arrangement.

The NAM module loads user-supplied Neural Amp Modeler .nam captures, while the IR loader handles cabinet impulse responses. AmpForge does not include either type of file. Buyers therefore need to source captures and impulse responses themselves; newcomers expecting immediately usable amp-and-cabinet sounds may find the initial setup incomplete.

Autotune pitch correction and a de-esser extend the plugin beyond guitar. These tools are practical for sessions that also need basic vocal correction and sibilance control, although AmpForge is not presented as a full vocal-production suite. Preset management is well covered: users can save, update, delete, export, and import custom presets, and factory presets are included.

Pricing

AmpForge: free. The plan is a free, open-source plugin for Linux, Windows, and macOS. There are no paid tiers, seat charges, quotas, trial periods, or renewal terms to weigh. That makes it a straightforward choice for users who want to avoid licensing costs, with the trade-off that the project does not supply the NAM captures or cabinet impulse responses needed for those loaders.

Platforms

AmpForge runs on Linux, macOS, and Windows, and is offered as VST3, LV2, and CLAP plugins. A standalone app is available on supported platforms, and the project describes host use with Reaper, Carla, and Bitwig. Windows installers provide VST3, CLAP, and LV2 formats but no Windows standalone executable, so Windows users must use a compatible host for standalone-style work.

The macOS build is not code-signed or notarized. Installing it requires the Gatekeeper workaround described by the project, adding a security prompt and a manual step that will matter to users who prefer conventional signed software.

Who it's for

AmpForge fits guitarists, home producers, and sound designers who value an adjustable pedal order, deep host automation, and support for their own Neural Amp Modeler library. It also suits users who want guitar and basic vocal effects without buying a separate plugin. It is a weaker fit for anyone seeking bundled captures and impulse responses, a Windows standalone executable, or a frictionless macOS installation.

Pros and cons

• Pro: Nineteen reorderable modules and automation for every parameter support detailed, arrangement-based effect changes.
• Pro: VST3, LV2, and CLAP formats broaden integration across compatible hosts.
• Pro: NAM loading, IR loading, presets, autotune, and de-essing cover several common session tasks in one free project.
• Con: No NAM captures or cabinet impulse responses are bundled, so users must assemble their own sound library.
• Con: Windows has no standalone executable.
• Con: The unsigned, unnotarized macOS build requires a Gatekeeper workaround.

Alternatives

Browse Guitar Amp Software for a wider category comparison. Choose Amp Locker instead if you want a free core with a Prestige 1950 amp, seven pedals, and seven rack effects, while purchasing extra modules individually. GENOME is the better route for a freemium package spanning iOS, macOS, and Windows, with a free Intro edition and a 89.99 USD one-time full version. Pick IK Multimedia ReSing for dedicated voice and instrument transformation, with a free edition and a 129.99 USD one-time plan. Neural Amp Modeler is the more focused choice for an open-source NAM project across Linux, macOS, web, and Windows. Gjalla is another free, open-source option for Linux, macOS, and Windows. Soundshed Guitar is a free open-source alternative with no licensing, paywall, or extra purchases. Amped suits users who want a commercial freemium product, including a free Amped Roots edition and paid upgrades. Amplifikation 360 is an alternative freemium amp-and-effects platform for macOS and Windows.

Verdict

AmpForge is a strong pick for technically comfortable guitarists who want a free, open-source, highly automatable pedalboard and already have the capture and cabinet files to feed it. Its main reason to choose it is the combination of runtime reordering, broad plugin formats, and vocal tools at no cost. Look elsewhere if you need bundled sounds, a Windows standalone app, or signed macOS software with a simpler installation path.
