I used one for years.... only mod was installing an Eminence Cannibis Rex. I was one of two lead guitarists & I never was playing snappy clean tones. Lots of light drive rhythm then leads. Took pedals great. I loved it because I could turn it up & get some mojo coming out of it without hurting others (like I used to do with my Hot Rod DeVille 410). Sound guys loved it because I could throw it in a corner, down by a riser, up on a bar stool, etc... and just mic it pretty easily, no matter where it sat. Traveling as a 5 piece, load out with a B.Jr was much nicer than my old HRD 410. I think they are great --- for what they are. As long as you don't have unreasonable expectations, they are great.
