Darn. Shorting the switch in the pot and putting a new switch in is sounding more and more appealing.

Yes, you can either do that or use something like this:
the extra MOSFET is an inverter.
 

That still won't work with where the switch is. I'll just short the switch and add another.

Single supply with virtual ground? 
 
Makes single switches reallllly easy. 
 
Just cause objectivists are funny: its a good enough reason to use a virtual ground for me...

It had a virtual ground using a TLE2426, which was limiting the current supply to the opamp. I guess I could switch to a BUF634, but I could care less about objectivism, etc. I just want to get some more current through the amp.

Id lean towards a buffered rail splitter or something like it myself.

Any particular reason?
I was leaning away from it because I learned on my last build how much heat sinking the BUF634 really needs to put out much current.
Using the dual supply from the two batteries seemed sensible, what am I missing?

I tend to trust your advice, so I'm now thinking of building my cmoy with a switch like I mentioned, but since it's DPDT, I'll have it switch to dual supply on one side and buffered with an opamp on the other side, that way I can see what (if any) the differences are, acoustically. Regarding the buffer, would you recommend an opamp or an open loop buffer? I have one Buf634 and tons of opamps of varying quality. Also, what about  just a transistor buffered design? What do you recommend in the way of buffered rail splitters? You generally know best, so I want to go with waht you recommend.
