guitarix virtual versatile amplification for Jack/Linux
a virtual guitar amplifier for Linux running with jack (Jack Audio Connection Kit).
It takes the signal from your guitar as any real amp would do: as a mono-signal from your sound card. Your tone is processed by a main amp and a rack-section. Both can be routed separately and deliver a processed stereo-signal via Jack. You may fill the rack with effects from more than 25 built-in modules spanning from a simple noise-gate to brain-slashing modulation-fx like flanger, phaser or auto-wah,
or you can also select plug-ins from the large list of LADSPA and LV2 plug-ins.
Though we design guitarix with guitar-signals in mind there is nothing wrong with connecting a synth or any other sound-generator with it
Capable of producing some great guitar and bass tones, though has a somewhat steep learning curve.
This was another surprise, and a good one, too... It does take a very basic understanding of Jack to hook it up, but there is a choice of Guitarix/Jack tutorials on YouTube. Just be sure that your mixer has the levels turned up enough to hear things, and use (eg) Qjacktctl to connect the audio input and outputs to the system. Simples I had the audio too far up, and needed to hit the mute quickly due to feedback. Once hooked up, it works really well. Pretty darn intuitive... Trying it on an assortment of machines the main variable was the background noise - an HP netbook with 'Beats Audio' was OK, straightforward hissy input noise due to a piezo pickup mismatched to a (supposedly) Mic input with a pretty low impedance. An ancient desktop with an anonymous sound card was very good indeed. A 17" Dell Inspiron was quieter than the HP, but had issues with assorted CPU noises in the background. If you have similar problems a dedicated USB Guitar Input dongle (or box) is indicated, such as the Behringer 102. Not that cheap, though. This one is recommended by the Rakarrack folks, but there seems to be a wide choice of similar but less expensive options on Amazon. I've had fair results using a Terratec Aureon, intended for use with a microphone. Used it with a simple resistive pad and a potentiometer for gain adjustment. This too seems to have become mysteriously expensive lately. <sigh> There are indications on YouTube that Guitarix can be made to work effectively on a Raspberry Pi, which is exciting! Well worth having a go with this if you are into guitar/ukulele/music stuff. All praise to the devs!
The design is terrible if course (it's Linux) :) But the sound is awesome We need more guitar programs in Linux One great app and guitar player will switch to Linux
Guitarix is wonderful! The presets produce nice and juicy sound and the variety of effects is fascinating. Thank you so much, keep up the great work!
