gx_head is a derivation from the guitarix project and provide a simple guitar amp head interface, a tuner, a mono rack and a stereo rack.

In-build effects can un/loaded to the racks, reordered and saved as presets.

All Controllers provide a MIDI learn connection via JACK MIDI Presets can switch/load/unload with the MIDI program change message (any channel).

gx_head provides 3 tube models (12AX7, 12AU7, 6V6) and 8 different tonestack models(Bassman, Twin Reverb, Princeton, JCM-800, JCM-2000, M-Lead, M2199, AC30), so you can simply create the amp-model to your needs.

It comes with a bunch of in-build effects, like distortion, crybaby, autowah, phaser, flanger, echo, delay, . . .

The effects could ordered in two Racks, on for the mono effects, witch could be load for pre or post processing, and one for the stereo effects, witch could only used in post processing.

Effects are loadable over the menu, a pop-up menu in the racks, or a plugin bar. Settings could saved/load as presets. gx_head comes with some factory settings provided by guitarix/gx_head friend "funkmuscle".

All UI controllers could connected with jack midi via MIDI learn with your external MIDI controllers.

gx_head is ready for language support via gettext() and comes thanks to Pablo Fernández with a Spanish translation.
