Improve this schematic... a Boss DM-2!!!

[rocker-D82]

I draw the schematic of a DM-2 on my EDA software (gschem) to realize a PCB. But I hope to improve that before trace&route! Any suggestion?

[no one ever]

stereo?

I don't want to change the nature of the effect. I'm searching some trick (cap and resistor values) to make better pre and post filters. 

[A.S.P.]

what is: "better" ?

I believe that this design was made by fully competent engineers who already did a "good" work. Tell us what you don't like about the pedal, someone may be able to help you. But if you're just after a "better DM-2" and there's nothing wrong with the sound, it's better to leave it alone.
