Guitarix is an open source, versatile, virtual guitar amplifier running with jack (Jack Audio Connection Kit), a professionally-capable audio/MIDI server and master transport control.
Guitarix provides a virtual Guitar Amp composed of a pre-amp (controlling the gain, the drive and the output volume), and a rack where we can load a lot of different mono or stereo effects (dynamics, modulations, distortions, EQs…).
Guitarix provides one JACK input port and two JACK output ports. It is designed to produce nice trash/metal/rock/blues guitar sounds. Available are controls for bass, treble, gain, balance, distortion, freeverb, crybaby(wah) and echo. For the ‘pressure’ in the sound you can use the feedback and feedforward sliders. Guitarix comes with a GTK interface and as Ladspa plugin.
Guitarix takes the signal from your guitar as any real amp would do: as a mono-signal from your sound card. Tones are processed by a main amp and a rack-section. Both can be routed separately and deliver a processed stereo-signal via Jack.
