Help identifying coupling caps

[megatrav]

I have 2 Citrus Press (JHS Pulp n Peel) boards from Effects Layouts.
I am going to build one as stock but I would like to build the other as a the “Lime Aid” version.

Josh Scott mentioned on a Facebook post that the only difference is the coupling caps.

I know that increasing the value will allow more bass through.

So, I need some help identifying which are the coupling caps

C1, C4 and a maybe C2
Increasing would let more bass pass
Decreasing C7 and C9 would restrict the bass.
Not sure what the Lime Aid is, more/less bass
You'll want to do the math on any filters these caps are part of as well.

You could tweak the filter in the feedback loop of IC1B as well as I don't think it's doing anything.
