Hi all,
Hoping someone can point me to the right direction on this. I’ve been wanting to build a Tube Screaming Preamp (really dig the 3 band active tone control) and MKC combo with a order switching board included so I can switch which effect comes in the signal path first. But while I was planning the build, I started to think what if I want to add something like a wah in between the 2. How do I go about wiring a set of send and return jacks in between the 2 so that it’ll always sit in the middle no matter which effect comes first in the order switching board?
Appreciate the help anyone can provide.
Thanks in advance!

A proper pair of ¼” switching jacks should do the trick. I’ve used these from LoveMySwitches successfully.
Note the schematic of switching mechanism of the jack. Use the tip switching to bypass the signal when no pedal is inserted.
Perfect, I actually bought some from Love My Switches not too long ago! So do I wire the “Send” jack to the output of effect 1 and the “Return” jack to the input of effect 2?
Sorry. I just removed my post because I realize it won’t work. I fought over this for several hours and just can’t figure out a solution.
Anyone else?
What I couldn’t solve was how to get the effects loop to always be between the 2 effects.
TBH, I may have over-simplified something that is a bit more complex. Using only switching jacks with an Easy Order Switching board is not straight forward. The FX loop that two simple switching jacks will always follow one of the selected orders using the EOS brd. So while in one state, that FX loop will be in the middle, but when the order gets changed, it will not. I need to put my thinking cap on longer for this one.
A couple years ago, Wilkie posted this nifty little contraption . . . the stomp switch is actually a 4PDT stomp. I’m hoping somewhere in there is a real answer.
Yeah, the part I couldn’t figure out was how to keep the FX loop to stay in between to 2 boards with the order switch board added. And I really don’t want to get it too cluttered with too many switches and wires, so to keep things simple I think I’ll just stick with having the FX loop come after the first board.
Cybercow and Wilkie thanks for the help and suggestions, much appreciated!

I am relieved that there was no easy answer to this. I have a couple pages of scribbles trying to figure it out before I gave up. I was starting to think about the 4PDT footswitch or toggle for this when I quit. That diagram from Wilkie above looks interesting! On a positive note, I think I figured out how to wire a selection of 3 different caps using a DPDT on-on-on switch in a way that I had not considered before while trying to think through all this…
Will be very interested what someone figures out on this. In addition to the circuit the OP wants to build, I think it would be interesting to build into a utility box with 3 send / returns.
I guess I can be a bulldog when I get a challenge like this. Lost a bit of sleep, but I think I found an easy solution. It will require adding one extra DPDT switch in order to move the new effects loop into position. I hope BlackatChicago doesn’t give up on this now that everyone is excited to find a solution. Add the extra DPDT as shown below:
I know I should probably be able to tell from the diagram but what happens if you don’t click the additional switch when the order is changed?
Hmmm. Thanks for asking. Now I see that the DPDT needs to be a 4PDT so that it will also direct the unused effect directly to the appropriate FX utput jack.
I will post a revised diagram shortly.
Well, I think I got it right this time. Disregard my previous diagram. Connect the points in red to the Easy Order Switching Board. You should have an external effects loop that stays between the effects when the new 4PDT switch is actuated with the order switch. If you do not switch it, the loop will still stay after the previous effect selected.
Hi Wilkie, thank you so much for taking the time and solving this! (Kept me up for a few nights before I posted here ????) One more question, should I be using a 4PDT On On like this one from Love My Switches?
BlackCat – that toggle (in your link) will work. But if you want it as a stompswitch, use this one.
Yep! This was a tricky one! Let us know if it works to your satisfaction. If not, I’ll just shoot myself in the other foot.
