Hello again, tech help genuises. I recently built, or, rather, attempted to build a brian may treble booster generously supplied by rullywowr. (build doc here https://dl.dropboxusercontent.com/u/73135424/Brian%20May%20Treble%20Booster/Brian%20May%20Treble%20Booster%20Build%20Doc%20v1.1.pdf) I did something wrong, naturally, and I'm trying to troubleshoot this build. Here are some pictures of the completed circuit.  <a href="http://www.flickr.com/photos/23187848@N07/9690649323/" title="DSC01966 by andrewbrautigam, on Flickr"><img src="http://farm4.staticflickr.com/3758/9690649323_6538e85f45_c.jpg" width="800" height="531" alt="DSC01966"></a> The testing rig output probe works at c1, but nowhere else. help?

Hi,

R2 is wrong should be 100k but seems to be 10k
You should also reheat and reflow all solder joints that still show the golden pad as it looks that it was not hot enough.

Sorry for the newbness, but is that a good marker? if the joint shows the solder pad, it wasn't hot enough?

Usually, when you solder you put the tip of the iron against the pad and the pin of your resistor. Then ideally both heat up. Then you give the solder to the tip and the flux will help to distribute the solder evenly across the heated material.

This is the ideal scenario. If there is not enough heat it will not happen and look like some in your pictures.
