True Bypass Dual Looper

[paLLo]

Hello Anyone...
  Im looking for a wiring diagram on how to make a True bypass, dual looper, with led's.  Any suggestions?  Links?
  I figured this kind of thing would be all over the web, but its not.  I can piece together hints, and suggestions, but not a full diagram.
  Im a newbie to DIY, and so far have built only one simple fuzz pedal off of RG's site.  I figured the dual looper would be a nice easy project, and I need one as well.  

I would appreciate any guidance as to websites offering such diagrams.

Thanks

Wow. that's an explanatory site!

I build one that switched loop A in and out, and loop B in and out.
At work right now, so dont have schematic.
I basically used a schematic from Fulltone, go to their site, got to tech tips and answers and there is a PDF file with an a/b box.

In the end I build two loopers in a row to get the switchable loops.

So if you take both the Fulltone and the other site, you should have enough information to build yourself a looper.

Come to think of it, i build two bypasses  using the usual 3dpt bypassing.
If you take a look at the Krok feedback loop. just take the loop and build it twice (or more times). The output of one is the input of the next.

good luck!

Thanks for the hints.  I found plans on

This shows exactly how to build one looper, or as many as you want.

I made mine a dual looper, housed it in a very small hammond box, from small bear electronics.  It came out great.  I gave it nice leds, too.

A white for one loop, a green for the other, and a flashing violet LED that blinks when the unit is powered up.   (i know, i know.......totally unnecessary...but when i look down at my pedalboard it makes me happy to see as many lights as possible, plus it was a fun thing to add.)

I learned about flashing LEDS here:http://http://wolfstone.halloweenhost.com/HalloweenTech/anemak_MakingLEDEyes.html#SimpleBlinkerEyes
 
Pretty neat.!

Thanks for the tips.  The project was a complete success, and I got great satisfaction from making something out of almost nothing.....and I think thats what its all about.

Congratulations! Nice to hear it all worked out. Thanks for the blinking LED's page, I'm a big sucker for lighting up my pedalboard as well.
