Congrats! I've got the Neo 115 Bassman cabs. Mostly use just one. They sound great.
Old Bassman cabs, I can't speak Much for. I've only used the old pyramid 412, which wasn't much chop.
The Orange 115 is pretty much an EV TL606 cab, which are great. Im sure it'd sound great with the Super Bassman.
Can't say enough good about the Bassman Pro Neo 115s tho. Superb. See many of my posts in this thread that praise em.

I totally agree with Rod. Neo 115 is perfectly voiced for this amp and if you're going up stairs every time it's about as light as a cab gets. No worries about cranking the 300 watts either, the neo takes it all.
