Interesting... Do you run your rig into the pa or into your amp?

I run it into my amp, and also split the signal into a USB audio input for recording, and I use monitor speakers. I don't have a PA since I don't gig, just mess around in the studio for now.

Overall my opinion on eurorack as a guitar effects is that standard pedals are probably better and more powerful (and loads cheaper)... However, having all the patching options will let you make different and interesting sounds.
