Having recently bought an M-Audio soundcard with several input/outputs i decided to plug in my electric guitar to see how it would sound. Whilst playing with renoise i notice the audio input function, so now im using renoise as a guitar fx box aswell as a tracker. The ability to automate diffrent fx add’s for endless fun (also costs a LOT less than a standard stomp box would) 
which effects are you using
I don’t own a guitar, but using a mic in a line-in device + effects & recording in the sample editor = endless fun.
Ive just been messing around with the internal fx in renoise. … combination of lo fi, filter, distortion, reverb and compression makes for a huge wall of noise
Yep, I am using an Electric Guitar with Renoise too!
But before you do that, you have to post some fx-chains and presets with us.
