Mini booster wiring trouble

[mnordbye]

I really can't figure out what "A" and "B" connects to or do. Can anyone tell me the secret?  They go from one end each of the 100uF cap..

I think they are extra connections included on the circuit board he sells for if you want to add some sort of  gain control or some such other thing. You can ignore them and the circuit works as usual. Maybe also they can be used as a low impedance buffer output?

I guess you're right about that, an optional variable of some sort. I've seen many versions of this circuit, but i guess i'll just leave those connections open for now. Thanks man.
