Removing the 0-001 capacitor connected from the top of the level control pot to the wiper in that line out circuit would likely reduce the treble somewhat. The effect of that capacitor would be to boost the treble, especially at lower level settings. You could also experiment with a capacitor and potentiometer connected in series across the level control pot.

I've used this circuit on my 1955 B2/Trek II preamp and it's pretty nice. I have noticed that it's a little trebly in output so I've wondered if there's an easy way to add a tone control to tame it, or a crossover to create a subwoofer output to emphasize the bass/pedals. Of course, a way to feed the signal back into the Leslie to create an effects send/return loop would be great but I expect that that would be a bit more complex.

Also, Kon's Zener diode overdrive circuit is floating around out the in the internet, and on one of my hard drives, somewhere.
