I've got all voltages on track but the LFO is not LFOing...  I think at this point after 10-12 hours of troubleshooting that the board is pretty much pooched so I'm going to pack it in on this one.  I thought I had pretty good troubleshooting chops but this one is a head scratcher.

I think I jinxed myself by finishing the case first and then building it.  :-\

Scruffie I'm back.  Good to be busy, but it's eating into my pedal building time  :P

Anyway, here's the report so far.  I'm running the pedal from a regulated 9V source.  All is in spec till I get to the front of IC4:

1 - 2.222v
2 - 2.222v
3 - 2.010v
4 - 0
5 - 7.36v
6 - 7.39v
7 - 7.44v
8 - 14.78v

It all goes goofy from that point on.  All components before IC4A look good.  Any ideas?

Sounds like a new Frito-Lay product.  Anyway I've built up the Collosallus and I can hear a distinct short delay but no modulation.  My voltages on IC4 and beyond are pretty messed up and all controls don't really appear to do anything.  Board and parts are triple checked so I suspect a chip or trans. Could the 4013 be creating the havoc? I'm getting delay so suspect the MN4007 is good (although voltages are off).  I've swapped out multiple 4049s.  I'm banking on the fact that I haven't torched the 4007...

I can post numbers if needed but before I order more 4013s (only have one on hand) I thought I'd see if anyone else ran into this.

Move to Canada and then look into ludicrous costs for shipping...

Ha!  Worse yet have them spell Saskatoon, Saskatchewan!  I moved to Chicago...much easier to spell...and better shipping costs.  ;D

I've been using Amplitube 3 free for practicing and learning tunes.  I got the THD BiValve model and it sounds really good, and the whole setup is nice and simple.

+1 with the Mammoth ones.  It's been sporadic (so far only a few out of an order of 50) but it seems to be based on a loose connection with the rivet holding the ground lug.  If you squash it (carefully) with a pair of vise grips, channel-locks, or pliers it should solve the problem.

You could be like Microsoft and just call it HoneyDripper Vista... :D
