It's More Than Phase Shift

"what's the big deal about having tone controls then? The answer is they cause phase shifts"

I'm a fan of tone controls, they can indeed be very useful at times. Nevertheless, I don't agree with the above conclusion. Whenever feedback-based tone controls are introduced into a circuit, sonics become modified by both the additional coupling caps and the transient distortion created by feedback. The latter, in particular, is IMO one of the great contributors to the degradation that occurs when one moves from a short-path, all triode amplifier to pentodes. If a circuit as complex as the one posted here does not cause a loss of nuance and smearing of details when inserted into a system, the system needs improvement.
