For cheap solutions I think OTAs, tubes and guitar circuits are the answer.

But if you can define what the function is that you want to give you 
your warmth there might be a solution but more complex than a single amp.

Diodes doing a piecewise linear circuit to approximate what you want 
might work. Also check out Chapter 1 Function Fitting in Analog Devices 
Nonlinear Circuits Handbook for other ideas.
