DIY True Bypass Looper

[cLepto-bass]

Hey all. I am thinking about building my own single channel true bypass looper pedal which will be used to switch on multiple pedals at once. Hoping to keep it simple at this stage - just one switch with four jack inputs in a small box (not even interested in an LED). Just wondered if anyone has any experience in this build and maybe point me in the right direction of build diaries, components, schematics etc etc. Cheers.

wire all of the grounds together (the bits that touch the long (sleeve) part of the 1/4" leads), then connect the others (tips) to a DPDT footswitch (double pole, double throw) - the connectors look like this (crudely illustrated)

______
| 1 2 |
| 3 4 |
| 5 6 |
----------

Input goes to lug 4, output goes to lug 3. wire lugs 5 and 6 together, then wire pin 2 to the SEND socket, and lug 1 the the RETURN socket. Ultimately, as long as the INPUT and SEND are on the same side, and the RETURN and OUTPUT are on the opposite side it doesn't matter which way around you do it, just as long as you mount the footswitch vertically.

good quality footswitches and jack are available from loads of different suppliers (you can also get them off eBay, but it's a bit hit and miss on quality on there at the moment)

Reputable suppliers are fuzz dog's pedal parts

for example.
The toughest bit about building a box like this is drilling the enclosure (assuming you're going for a metal one).
Don't forget to tin your wires!

If you did decide you wanted an LED, great layout here:

Or if you don't want an LED, then as a visual alternative to Pauls post above:

I use one of these (there are several makes available). Start with a 4mm hole then ream out to the required size [i]VERY SLOWLY[/i] as it is easy to make the hole too big!
Stop and check size frequently. Cuts through diecast boxes like butter.
