I think ecasound would be an excellent choice, especially as you are low on 
CPU and ecasound does not require guis and such stupid things. :)

Do remember that ecasound supports LADSPA plugins so you are in no way limited 
to the built in effects of it.

Other alternatives could be Jack-Rack (which is also for LADSPA effects) if 
you fancy GUIs. I think there are some ready-to-go boxes on Dave Phillips 
site also, for guitar, you know: <comp><dist><mod><del><rev>. But I haven't 
tried any so I might be mistaken.

One thing to think about, that I don't know the best solution for, is if you 
want to alter the parameters in realtime. To get Wahwah or some cool organic 
modulation effect. 
First you need an interface to an external pedal, which isn't so hard, they 
generally produce midi. But I'm not sure about the best software. You'd 
basically want an effect rack with midi-in.
Possibly there are some small midi only app that can be used to remote control 

Ok, now I've strayed far enough from the subject :) Have fun.
