Induction - are you using LTSpice?  I've been using it quite a bit lately to develop an amp sim and it's been a great tool.  I even have Spice models now for all my favorite JFETs (J201, 2N5457,...)!

As for the tone control, it's pretty much a simple treble cut, so as Induction says, play around with the pot/cap values.   Anything more sophisticated would be lossy, but since there's a gain stage following, you could increase the gain there to compensate.  The second order filter at the output also rolls off high end so if you want more treble, you can play with those cap/resistor values.
