I might be looking for a modelling amp I can use with my stereo pedals. So it needs to have stereo ins and outs and possibly but not necessarily be used as an interface. Would it work if there only were stereo effects loops? I could put modulation, delay and reverb there and mono drive pedals in front. I know there is Eleven Rack, but what else is there, that doesn't cost a zillion (like kempers and such)?
