Hey fellow builders!

I've built an easyvibe from this layout:

The lights are glowing/pulsating.All the pots are controlling rate and depth....but either I get (at best) just the guitar signal with no modulation or no sound at all (whether i'm in chorus/vibrato mod)
As far as I checked the wiring, pots and that the effect seems to work ok (well...virtually)...I turned clueless... ???
ideas anyone?  :icon_idea:

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

You have the LED's facing the LDR's, aye? Then cover the whole unit to shield it from light. If you have the LDR's exposed to light, you won't get any variation. If that's not it, then follow R.G.'s advice and report back on this thread with the information needed.

I still catch myself wondering why an LDR circuit isn't working and have to resort to a slap to the forehead as punishment for my simple oversight.
Give a man Fuzz, and he'll jam for a day... teach a man how to make a Fuzz and he'll never jam again!

yes R.G...I've read the article.
But all that I had to get was...a functional brain (and maybe some magnifier) :)
All the soldering and wiring was good...except that I soldered 2 ldr on the wrong raw....my mistake!
anyway, thanks for your support guys!You rock!

cheers!
