3-Legged Dog - Probing Question...

[mydementia]

Hi guys.
I've been on a 'modular' kick lately and started making layouts that allow me to mount the pots directly to the board - I did a May Queen Booster that turned out great (can't believe I hadn't built one of those!).  I made the layout below for the ROG 3 Legged Dog circuit - awesome sound clips - and another one I can't believe I hadn't built yet...

I perfed one up... great tones - but there's a LOT of noise.  I got out the handy audio probe and started checking around... all sounds good through the J201, sounds good into pin 7 of the CD4049 but is noisy as hell at pin 6...  since I was perfing, I ran wires (second picture, white) from the IC to the gain pot...
So - would a bad pot cause excessive noise?  Is it more likely due to my running wire in and out of the gain pot and the power drain resistor over both causing cross talk??  Any other thoughts?




Thanks for looking.

Nice job on the 3 Legged Dog.  Yes the May Queen is a nice sounding OD.  I really like it although I don't like the enclosure I put it in.  When you get the 3 Legged Dog working I would really like to know what you think of it.  ROG builds are great.  Almost every project that I've built from them has sounded great.  Sorry I'm no help with the noise problem.

you grounded pins 9, 11, 14 ?

Actually, I missed the ground on pin 9 (wasn't in the ROG PCB I used as a guide - shame on me for not looking back at the schem!!). 
I just grounded it, but it did NOT help my noise issue... good try!!

OK - not the pot - replaced with a fresh one and noise is the same... hmm...
