I think there a two very nice programs for guitar effects:

- jack-rack http://jack-rack.sourceforge.net/
- ams http://alsamodular.sourceforge.net/

for jack-rack effects: http://offog.org/stuff/racks/
for ams: http://www.lapoc.de/spinoffs/ams-guitrack-RFC1.tar.gz

usefull LADSPA plugins for the guitar http://quitte.de/dsp/caps.html#GimmeASetupAlready

for more you can always look at http://apps.linuxaudio.org/ or www.linux-sound.org >> Effects Processors

edit: I wrote two howto about using jack-rack and ams as effect processor, see section howto.

I like to know if you use guitar effects and which one (app and file..)

@ zettberlin, Have you ever tried other guitar effects? I hear jesusonic is used by reaper? Is it usable?
