Thanks Fahey for the great explanations. I learn much from them.
I've tried to simulate Little Rebel's tone stack as Roly suggested. (It's my first time with these softwares btw.) Yes, it has weird freq response.
I'll go for valvestate 10 then. Btw (maybe a silly idea) if I want to run the preamp from single power supply, say 12V, how to do it? Just as simple as connecting some bias resistors to op-amps?
