Low Output

I decided to re-house my Seymour Duncan Power Grid.  It is all SMD's. 

So I removed the pots and jacks from the PC board and wired them up.

Now it all works BUT the output is very low.  Weird.  Any ideas?

maybee some flux, or grease around the pot wire holes on the board is leaking some signal to ground? from removing the pots etc..possibly around the volume pot..
maybee theres a cold solder joint somewhere?
plug it in and wiggle the wires a bit? see if it affects volume
double check volume pot value...

nothing says forever like a solid block of liquid nails!!!

Interesting, The volume pot increases and decrease the volume, just the overall volume is very low.  I will check the short - ground issue.

FIXED!  It was a loose connection/solder joint for a wire at the bypass switch. 

Now I have a modern high gain active eq pedal disguised in a vintage 80's distortion box case.   :)
