High Pass Clipping for my J201 Overdrive

[SpringbokUK]

Hi all!

I built a neat overdrive circuit using 2 J201s. I got the gain of both transistors how I want it and biased nicely BUT I want to clip everything above around 700hz in the second clipping stage. So I took a 10k resistor and a 22nf capacitor and wired them parallel to form what I expected to be a passive HPF (and this is something I got from a Wampler book) and placed it after the output cap from the first transistor stage and it goes straight on to the gate of the second transistor and I got no filtering at all. It sounds the same if I just take the output cap from the first transistor and wire it directly to the gate of the 2nd. 

So then instead of wiring the resistor and the cap parallel I take one leg of the resistor and take it to GND, which is what I normally do. Now I have results but now I'm losing substantial volume so that's no good.

I've attached an image of what I know from the Wampler book. This is what I tried first with no results. From what I have read, there is nothing in the text that says anything more needs doing for that. Just place it before the gate of the transistor and whatever freq cutoff the RC combo has then that's what will get clipped.
That's how I understand it but I am probably very wrong! 

I have thought about putting in an active hpf but ideally I want to keep the circuit to a minimum.

Show me the way!

You're probably losing volume with the second approach because the resistor value is too low.   Try like a 1M resistor to ground and 220pF capacitor.  The resistor value needs to be a lot larger than the drain resistor value of that first stage, otherwise it's going to load down the output of the first stage.

Yes mate good shout!
