I recommend tantalum for C11...

Newb question: Just curious what the difference would be and why you recommend tantalum?

Lower leakage, lower noise.
The difference between aluminum & tantalum will most likely not be audible in this case.

I forget where I read it - maybe it was here! - but apparently the reason Paul C made the VREF voltage splitters asymmetrical was to help guys using batteries which were running low on voltage.

My explanation of the asymmetrical Vref is: it allows to maximize headrom if there's an asymmetrical clipping in the circuit.

Smells more like rumor than fact to me. Cochrane is not the only one to offset Vref. Look at the series of BE-OD / Dirty Shirley pedals.

Well I won't be repeating that nonsense again!
