...ran your multifx unit into your stereo? I just plugged my Boss GT-8 into my mixer, which runs into the computer. My computer "speakers" are my stereo system. So I'm listening to my guitar thru the stereo and it sounds great. Makes me wonder why people need a good "bedroom amp" if they have a stereo. I write this as I stare at the 6 amps I own!

LOL, not literally they're actually scattered about.
But it did get me to thinking that for someone that only plays in their bedroom or den, you can go a long way or your electric with an FX setup and a stereo before actually "needing" an amp.
