It look very cool. That said....
1) I hope I never play in a bamd with a guitar player who shows up with THAT thing. 200 tube watts and SIX TWELVES???? No thank you. There aren't enough earplugs in the world to make me want to try keeping up with that.
2) Back then, in many cases, there weren't a ton of differences between bass and guitar circuits, or bass and guitar drivers/speakers. I bet it would sound great for bass if you're into an old-school vibe. Is the cab open or closed back?
If I recall the sunn models correctly the 100S/200S and 1000S/2000S were guitar/bass models in this fashion. The 100/1000 had trem and verb but the power amps and much of the preamps were the same. 100/200 were 2 power tubes, 1000/2000 were four.
