What brands tend to have the worst resale value?

I couldn’t resist this topic which obviously contrasts with the post on the other side of the equation.
In all my years buying and selling gear I think that Soulution gets hammered more than anything I’ve ever witnessed. I’m sure it’s great gear so there’s something that I’m missing. Mola Mola looks tough as well. Late generation Krell pretty weak too. 
What are some other candidates?
