Multi-Effects Problem - Super Low Signal :(

[Wedge]

Hey guys, I snooped around here for some info for quite a while, but now I've run into a problem and I hope you guys can help me out with it!

So a friend of mine asked me to help him with a project - he had an old Line 6 DL4 that had broken and he wanted to fill it with new stuff!  So what we settled on was an MXR Blue Box, a General Guitar Gadgets Green Ringer, a BYOC Reverb, and a BYOC Confidence Boost, wired in that order.  So I got everything put together (including reattaching the battery connector to the blue box, because apparently it needed a battery connected to work, even with 9v), and I get no signal.  However, when I ran a really hot signal from my laptop headphone jack through the pedal, I can get it to come out through an amp - it's just really quiet.

Does anyone know what might be causing this?  Other potentially relevant information: I just have 1 input jack, 1 output jack, and I'm just using 1 DC jack, powered with the output from a Gator regulated power supply.  The way I tried to figure out how to wire it was I wired every part of each pedal that was supposed to be connected to say the sleeve of the input jack together, and then ran one wire from that to then sleeve of the input jack (save for the tips of the jacks, which I used to run the pedals together). 

Also it could be important to point out that the wiring of all the pedals were at least somewhat different - some had led holes on the circuit boards and some were wired directly to the switches; the ways the switches were supposed to be wired was different, etc., so it very well could be an error in how i connected them together.

Thanks so much!!

sorry.. http://www.diystompboxes.com/smfforum/index.php?topic=29816.0

I would start with each effect and test them on their own.
Can you post a block diagram and switch connections or pictures and some voltages.

There's nothing wrong with your pedals .
It's because of a violent impedance mismatch , i attempted to try it before .

Eeee, "Violent Impedance Mismatch" doesn't sound great.  Is there any way to fix this or am I pretty much screwed?

You could have impedance issues, but you need to test each pedal on their own, ensure they work. Then with a good bypass system they should still work one at a time.

Then we can trouble shoot impedance issues..

Most pedals do 1M input 10k Output .
If you are testing pedals all the time w/o a guitar you need a 1) Op-amp buffer ( not sure if mine is overkill or not   )
( that was mine )
Change the 1M to 10k for computer outputs .

Right .... before you build it , i have a question , are you a guitarist ?
If you tested it first on with a guitar looks like the pedals aren't really working well and a buffer won't help .

This enforces what Steve talked about testing each single effect.

Then... is there any kind of effect bypass?
If you have no signal with effects bypassed, you have issues with your wiring for sure, this may not exclude further board errors.
