Need help Blues breaker

I built this General guitar gadget Blues breaker and it worked fine for about two weeks. And then one day no sound came out of it when the fx was engaged (the led still works) but got sound when it was in by pass. I figured out that the diode in d5 was bad, (a little blue one) I was getting a reading from both directions. So I went down to radio shack and bought a 1N4001 and a 1N914 because the kit said it could come with either or. And I tried them both and neither one fixed the problem. I'm kind of at a loss because it doesn't seem to fit any of the debugging symptoms. I also checked all the solders and connections.

I should also mention the 1N4001 diode I purchased looks differant than the the one that caime with the kit...it's black w/a gray stripe

Thanks,

Scott

you have to list a few more things, does the led work when effect is engaged, did you put in any mods, have you tried the PS(or battery) with other pedals, are there any parts that could be grounding out?  and if you can take voltages.

IC1 (or U1)
P1
P2
P3
P4
P5
P6
P7
P8
.

D1
A (anode, the non-band end) =
K (cathode, the banded end) =

D2
A =
K =

etc...

Battery: good
LED: works
sound when bypassed
No mods
Not sure if I replaced bad D5 diode w/correct one.?
solders and connections appear good w/no grounding.

Not sure what your asking here..I'm a noob?

No worries! This thread is for you: DEBUGGING - What to do when it doesn't work (http://www.diystompboxes.com/smfforum/index.php?topic=29816.0)

Thanks for the link. I guess I need to look a little harder I missed this some how.
This is gonna take some playing around on my part I'm not to savvy on the multimeter...but this is why I'm building these FX to learn.
