A free guitar rig for Windows, macOS and Linux. Plug in and play through your own plugin amp sims and pedals. No DAW, no session to set up.

Reorder, bypass and swap modules like pedals on a board. It runs live, at the lowest latency your interface can do.

What you get

• Your plugins, any order. Any plugin amp or effect, from any maker, in any chain: a free overdrive into a commercial amp sim into whatever reverb you love.
• Thousands of real amp captures. Browse the library and load a capture without leaving the app.
• Two amps at once. Split the chain into parallel paths, each with its own volume, pan, mute and solo, and merge them back.
• Only the controls you use. Map the few knobs you actually reach for onto the module card and hide the rest. Save the layout as a patch and reuse it.
• Save and recall. Save whole rigs (chain, routing, every plugin's exact settings). Your last session restores on launch.
• Practice tools. Tuner, metronome with tap tempo, and a looper, all built in.
• Ready for the stage. Setlists load a rig per song; scenes, MIDI learn and a stage view run the set from a footswitch.
• Yours, with nothing attached. Free and open source. No account, no DRM, no iLok, no telemetry. It phones home only for an anonymous update check.

Install

Grab the latest installer from the releases page:

• Windows 10/11 (64-bit): run Plectrify-win-x64-setup.exe. Everything it needs is bundled.
• macOS (Apple Silicon, 13.3+): run Plectrify-macos-arm64.pkg. It installs the app plus the VST3 and AU plugins.
• Linux (x86-64; Ubuntu 24.04, Debian 13 or newer): install Plectrify-linux-x64.deb, e.g. sudo apt install ./Plectrify-linux-x64.deb. It adds Plectrify's APT source, so updates arrive through Software Updater / sudo apt upgrade (from 0.1.7; older installs need the newest .deb installed once).

Important

The macOS build is signed but not notarized, so macOS blocks the installer at first and may claim it "is damaged". It isn't: go to System Settings → Privacy & Security → Open Anyway, or see the full instructions. Every installer ships with a SHA-256 checksum you can verify.

Bring your own plugins; plenty of great ones are free. Neural Amp Modeler is included, so TONE3000 captures play with nothing else installed. On Windows, install your interface's ASIO driver for the lowest latency; macOS uses CoreAudio; on Linux pick JACK (PipeWire's JACK works) over ALSA.

First five minutes

1. Open Audio Settings and pick your interface as input (the ASIO device type on Windows, JACK on Linux) and your speakers or headphones as output. The first enabled input channel is your guitar.
2. Hit Scan Plugins once. Plectrify finds and remembers your plugins.
3. Add modules: an amp sim, then whatever effects you like. Drag to reorder, click to bypass, open a plugin's own editor from its card.
4. Map the knobs you care about, save the rig, play.

Feedback and bugs

Open an issue or say hi on Discord. For bugs the fastest route is in the app: Report a bug opens GitHub's form pre-filled with an environment report (build, machine, audio device, plugin chain, never rig names or file paths).

For developers

Plectrify is a JUCE 8 (C++17) plugin host, with the entire UI a Svelte 5 web app in an embedded web view.
