+Guitarix takes the signal from your guitar as a mono-signal from your sound
+card.  The input 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 including stuff
+from a simple noise gate to modulation effects like flanger, phaser or
+auto-wah.")
