AmpForge is a guitar amplifier simulator and multi-effects processor built around an internal pedalboard rather than a collection of separate plugins.
It can run as a standalone application or inside a compatible audio host, with the complete signal chain managed from one graphical interface. Pedals can be added, removed, bypassed and reordered directly in the rack, making it suitable for constructing both simple amp tones and more elaborate processing chains.
Although guitar processing is its main focus, AmpForge also includes vocal-oriented modules. Users can disable the amplifier and cabinet stages and combine pitch correction, de-essing, delay, reverb and other processors for vocal work.
This is free and open source software.
Key Features
- Provides gate, compressor, wah, overdrive, distortion, amp, cabinet, modulation, delay and reverb modules.
- Loads Neural Amp Modeler capture files as a dedicated block with mix, input trim and output trim controls.
- Offers Modern, Vintage, Crunch and Hi-Gain amplifier voicings with distinct tone and clipping characteristics.
- Supports cabinet impulse-response convolution for speaker and cabinet emulation.
- Includes Autotune, De-esser, Doubler, Harmonizer and Exciter modules alongside the guitar effects.
- Provides tempo synchronisation for delay, tremolo and chorus effects.
- Includes a tuner that analyses the input signal independently of the pedalboard chain.
- Offers A/B comparison for quickly switching between two snapshots while adjusting a sound.
- Supports presets with save, update, delete, import and export facilities.
- Runs as VST3, LV2 and CLAP plugins as well as a standalone application using JACK or PipeWire on Linux.
