Adding a loop

[paul.creedy]

Would I be right in thinking that a circuit which has more than one connection to the power and uses a capacitor at the end of one section to separate it from the next (in terms of voltage) could have a couple of jacks inserted at that point to create a loop (with one jack including a switch to complete the circuit if nothing is plugged into the loop) ?

I'm asking this with the assumption that the (for example) two sections are essentially two circuits on one board so anything inserted between them wouldn't affect them other than how it would had they been two separate pedals with a third in between them.

It depends on what circuits you are referring to. A decoupling capacitor is between the power source and ground.. No need for a switch to complete the circuit when nothing is plugged in, just use a switched socket jack like this. When nothing is plugged in the contacts complete the circuit.



As a rule, I never make assumptions where electricity is involved.. Even with low voltage/current that you find in most pedals, it's just good practice.. If you are thinking of throwing an fx-loop between a preamp and power amp or whatever you may want to use a simple buffered loop which you can pull up thousands of variations of on google.

I'll be more specific then

Here's an example of the type of circuit I was thinking of.



There are two caps together in the middle of the circuit which, if in two separate pedals, would make more sense than perhaps they do in this one, but nevertheless that looks like a perfect place to insert a loop, if someone wanted to see what would happen
