How do I mod my fuzz to be able to dial back to fuzz more and increase volume?

[switched on]

I got a great dirt pedal here and have never worked on a pedal in my life.  I thought I would ask you guys exactly what needs to be done and ask somebody local to do it for me.  I'm hoping different pots for the dirt and volume may do the trick...  All I want to be able to do is dial the gain back another 50% and increase the volume by 50% to compensate.  I would like not to change the tonal characteristics too much if possible.  Thanks.

The 9N3 Pot is the Gain Pot.

Being a rhythm player who uses fuzz is a nightmare.  Everything that sounds good to me has too much gain on tap for my needs.

If you take off the knobs, and take off the nut and washer, pull the pot out you should be able to read values on it. Keep the same taper (A,B,C) and increase the volume knob value to the next value and decrease the gain pot to the next value. At least in my understanding that would work fine.
