I just tried out my SG through a Sonic 2 head (same as 200s) going into a 215BH. This is my sisters' bass rig and it sounded downright scary with guitar, especially detuned. One of the sconce light fixtures on the wall fell off... the Sonic 2 starts to break up nicely around 7, so there was a good grind underneath all the low end. Don't know about any solid state amps, but I bet the 215BH has a LOT to do with the massive sound.
