A guy want's to trade me his Orange 412 for my Marshall 1960B 412 + $200

Worth it?
The Orange will have more low-end, and in my opinion it's of higher construction quality.

Honestly it all depends on whether or not you like the sound of your Marshall cab. If it was a straight trade I'd do it immediately, but the +$200 makes it a tougher choice.
talk him down to 150 and do it.

if you cant i say still do it. used 1960B cabs go for 400-500$ in my area. orange cabs go for atleast 700 used from what ive seen.

I think the orange cabs are superior to the marshall cabs too. just ebware, i dont think orange cabs have casters
Depends on what sound you are going for.
