I like my Nemmy, a whole lot. That it goes down to 2 ohms is a big plus. It's never given me a second of trouble. And the blue light is hawt. But the eq on the 550-B is sooo versatile, and it sounds so good. I haven't a/b'ed, but I understand the Funk is a really underated 550 watts in terms of loudness as well. I play Aggie cabs, GS112 x 2 (1 NT), and an S410, all 8 ohm, and main bass is a Fender P/J. Should I take the gassy plunge?
