I put this on a Fender Super Champ 1x12 cab and it sounds amazing. The clean version is perfect for testing out different pedal combinations. Not sure if the rock or AC versions would be good for that. Will it replace your AC15 or 30 or even your Fender Hot Rod? No, but the sound of the MV50 Clean far exceeds the price.
Def. loud enough to play gigs if you needed to.
