Re: 'Pre-gain' control for Tonebender Mark 3?

So, I tried adding the pregain pot, and it's...'okay'. It's not really smooth and the fuzz gets a bit flabby.

After some further research, I see that the Prescription Electronics also uses a 'gain' pot - but it runs the Gain pot between the Tone and Volume - so I'm not sure how I would add that. Below is the layout I'm using - I thought I could change the 68k resistor to 18K, and connect to a 50k 'Gain' pot (lugs 1&2), and connect lug 3 to Volume 3 - as is done in the Yardbox.

Any thoughts? Help?
