To Combine 2 Circuits, Do you remove the Output/Input Caps?

Ok, you got your soldering iron and nothing is going to hold you back, but you have no clue where to start or what to build. There were others before you with the same questions... read them first.

Sorry, I know there are a lot of "combine 2 effects threads" but I couldnt find one that addressed this specifically.

If I want to combine the 2 circuits in the top drawing, do I leave the clouded section in, or do I remove the output/input caps and pull down resistors and join them as in the second drawing? I know just hooking the input and output together would work, but are the extra caps necessary since the signal is already converted to DC and doesnt need to go back to AC until it leaves the second effect circuit?

Many thanks in advance for any conformation/correction and any elaboration on why!

Octave circuit (with home made darlington pair) > Emitter follower > LPB1 (because that Octave looses almost all gain) Im sure there is a better way to do it, but in the process of investigating options I had this question and thought it would be a good learning point.

Can you explain briefly WHY I leave one of them to help me get my head around it?

It's what this guy has breadboarded here...

It's good practice to use a coupling capacitor between stages, so that you block any DC offset from the previous stage from "reaching" the next one.
There's no need to use two capacitors when one is enough :)
