  • True bypass looper pedal with tuner out/mute -- wiring diagram

    I put together a wiring diagram for a true bypass looper pedal with a tuner out/mute and thought I'd post it.
    You can set it up for as many loops as you can fit in a box. Just repeat the parts and wiring between
    loop switch 1 and loop switch 3.



    I know it's a simple thing but it might be useful to someone. I haven't actually
    built this - someone asked me about building one and so I put together a diagram
    for it. If you see any errors please let me know.

    Enjoy!

      I don't know if there are any errors,but it's well drawn and easy to follow.I built the same useing this diagram www.singlecoil.com/tb-strip/tbstrip.html

        I plan on giving this a try in the next week or so... I'll let you know how it turns out! Thanks so much for the schematic!

          Looks good!:thu:

          Are you sure you meant to use 10K resistors on the LED's and not 1K? According to my math, that comes out to around 1/2mA per LED. Will they even be visible with that little current?

            Please do! I'm looking forward to seeing it.

            Thanks a bunch for the drawing, Deaj! What do you use to do your drawings?

            I have a funky enclosure I'd like to put one of these into. Hmmm... another thing on my to do list.

              I made one very similar to this a while ago using the base TB Loop pedal from General Guitar Gadgets, drilling an extra hole, and getting another 3PDT switch. Works really well!

                You're welcome! I use CorelDraw X3 for wiring diagrams and illustrations.

                Another forum member requested a wiring diagram with a master bypass switch. I modified the above illustration for the following:. The first diagram shows a master bypass that includes the tuner out/mute and the second shows the master bypass after the tuner out/mute.

                  I have a large stock of super bright blue LED's on hand and a 10k resistor keeps them from blinding me when looking straight down at my pedalboard. For a standard LED a 1k resistor is definitely more appropriate. I just used a template illustration I had on-hand for the resistor. Thanks

                    I wish that some manufacturers (such as Behringer) would put the LEDs on the sides of pedals, or put something less blinding in them. I've been putting pieces of post-it note paper over mine until I decide whether I'm going to rehouse some or hack them to dim the LEDs.

                      Do you have a wiring diagram with out the tuner out / mute?

                      Thanks a lot.

                        Hi there,
                        sorry for digging up this old thread, but I could use a bit of help...

                        Thanks a lot for the schematic, I followed the first one, but with only 2 loops.
                        I have this problem: when both loops are on, I get a popping sound when switching off the 1st loop.

                        Does someone have a clue?

                        I'm quite a noob, but a quick learner
                        Thanks

                          Just to be more precise: what I call the 1st loop is the one closest to the tuner/mute 3PDT

                          So I get a pop in the amp when:
                          - both loops are on and I switch off the 1st one
                          - only loop 1 is on and I switch loop 2 on.

                          I am obviously new to this forum , and have already searched for (and found) popping issues when pressing a 3PDT.
                          But I have found nothing concerning more than one switch, or anything resembling my problem.

                          Any ideas, anyone?...
                          Thanks a bunch

                              The loops need pulldown resistors.
