I've had this for a couple months but finally had a chance to fire it up today. All I can say is if you're looking for small, cheap, light power amp that is sufficient to compete with a drummer - it's great. I play in a bluesey context, so not sure how it's work for metal with a really loud drummer but for me and what I do, I got to volumes that'd work fine for jamming at no where close to noon on the volume knob. Sounded same at that volume as it did at bedroom level driving a Cannibis Rex loaded 1x12". Great companion piece to your Amplifire.
