Hey, There is a music store selling a Sunn Concert Keyboard in my area for $300. I want to use it for guitar. I was just wondering if anyone had any opinions on this amp, and whether or not $300 is a good price for it, and also if anyone knows how much it weighs. Right now I have a Peavey revolution head, but it weighs 72 pounds, and sucks to carry around. I'm wanting to upgrade to something better that's really loud and has really nice cleans (good distortion would be a plus too, but I have plenty of pedals for that so it doesn't matter if it doesn't get distorted.
