What do these caps do?

[markbr]

Hey guys,

I have this Danelectro Honeytone circuit built on a breadboard but im not sure what these capacitors do:

1) C10 & C3

2) C12

3) C13

4) C5 & C14

5) C18

6) C1 & C2

I'll really appreciate your info because i've just started learning about amps Thank you.

C10 is decoupling the power supply to the op-amp.
C3 is decoupling the bias supply.
C12 is blocking dc and coupling ac - pin 3 will be at about 4Vdc (dc ref to bias), the vol pot will be 0Vdc (dc ref to ground).
C13 is rolling off some high end. The actual frequency will depend on the vol control setting.
C5 is blocking dc and rolling off some low end - pin 6 shares a dc ref with pin 5 which is referenced to the bias supply. The roll off will have it's -3dB breakpoint at about 150Hz at a guess, but will stop at a certain point as it's a non-inverting circuit.
C14 is doing the some role for the other op-amp.
C18 is a dc blocking coupling cap.
C1 is rolling off dome high end from the input.
C2 is blocking dc and coupling ac between the op-amp pin 5 and input.

Thanks a lot. I think i understand it a bit more now. What happens if i now supply a -9V to the -Vcc pin in addition to the +9V already being supplied? Would it be ok to remove R2, R9, R4, R3, C3 (biasing components) and C5, C14?
