GNUGuitarINUX is a GNU/Linux Live CD with a Realtime kernel aiming to be used as an electric guitar pedal effect.

GNUGuitarINUX v1.1_2 (w/kernel 2.6.33-rt)

The final version 1.1 is relesead. I am not very happy with the performance of the kernel 3.0 so I created another ISO image with the old kernel.

My recomendation is that you try both and keep with the one that gives you best performance :).
 The most important packages of GNUGuitarINUX v1.1 are:

 Based on Debian Squeeze (i386)
 Custom RT kernel - linux-image-3.0.3-rt11-gnuguitarinux
