The thing about "gain" is that once you have maxed out the gain available from the jfets, additional gain stages won't do you any good, except perhaps to give you more of a square wave sound. In any case, playing around with the source bypass caps should allow you to remove the "farty" sound from the bass frequencies. If you want to retain the mid-treble gain, try a 47 nF cap in place of the 1 uF cap in the first gain stage. If you use sockets, you can play around with this for all stages.
I'm not sure what is going on with your tone stack. It's a passive tone stack, so you can play around with the Duncan Tone Stack calculator to see if any mods will help. BTW, the 1 nF cap is a mid bypass cap - the rest looks similar to the Marshall tone stack (even the 22 nF caps - see the schematic below). I would just get rid of the 1 nF cap as an experiment.
Good luck. I can say that it is often worth experimenting and modding these effects to suit your tastes. I did this with the Marshall Shredmaster and it's now a very nice distortion box for me.
