Diesel Diefet - the quest: Weird tone stack response

The treble pot on this circuit reacts strangely, it seems to roll off far more lows than it adds highs, hence, it really sounds best completely off (making it useless). Surely there is a better way to make a treble pot.

I looked at Duncan - and it looks closest to the Marshall stack, but one difference, the mids here are 1n instead of 22n. The 22n (in Duncan) makes a lot more sense. If you plug in 1n the response is bad.

Anyway - any thoughts here? especially from anyone who has built this beast?

NOTE: I edited this to clear up some values, and to take out something I had said about pn4393s which seemed to be relevant before, but now not so much. So if you read it by email please re-read the part about the tone stack. Thanks.
