Help want to add booster to a pedal

[tomnottom]

I have built a, green ringer>Bsiab2>(want to add booster here)pedal. I started with the same thing with a FF clone in the center but did not like it. With that said I want to add a booster and am thinking a general guitar gadgets CB1 or SBB. I am thinking the CB1 because it can introduce some more gain per JD Sleeps article :Gain Changing Modifications

"The overall gain characteristics of this circuit can be tweaked by changing the
value of the 390 ohm resistor connecting from the emitter to ground"

My questions are :

1)what do I change the value too? I want just a slight gain up with the boost.
2)Would I be better served with a 100 ohm pot  wired in there?
3) would there be something better to use?

Random note thanks Zach for teaching me how to wire stomp switches so I could put multiple effects in one box.

Gain in a booster isn't going to mean "more distortion"... it's going to mean more volume gain.

I'm not looking at the schematic right now, but I think that if you want to increase the gain of that effect you'd make the 390R resistor smaller.  Note that if you make it too small the boost is no longer going to be clean, as it will be trying to amplify the signal more than the 9v power supply will provide.

How would I introduce a little more distortion in this circuit (CB1)?

Booster before the BSIAB2?
