Ok, so this is not the first time I have done this and I am not sure why it's not working now.  I have two piezo discs wired in parallel.  Both hot leads are together and going to post 1 on my 250K volume pot.  The negative leads are together and soldered to the scraped back of the same volume pot.  Middle pole on the pot is going to the inner post of the jack, and the post connection of the jack is going to the back of the volume pot.  

When I turn the volume all the way up... nothing.  When I turn it down... nothing.  In the middle on the volume, I can tap on the discs and I hear sound.  

Now, the sound is faint coming from these discs. These discs are about the size of a nickel and I have used them before this way for a decently loud sound.  What gives?

When I used piezos in parallel, I did it differently. Instead of each + wire from piezos going to the potentiometer, bridge the two piezo + together, then continue from one of those to the pot. In more basic terms, from piezo 1 + to piezo 2+ to potentiometer lug. 

Would bridging the piezos together not wire them in series?

Or are you saying to take a chunk of insulation off in the middle of one of the positive and negative wires and solder the one negative lead to that spot (and the one positive to the place on the positive wire) so that I only have one wire going to the pot? This seems more similar to the 3rd image attached. I just did this instead (see attached).

Here's essentially what I did. Why wouldn't this work?

Have not done much work with piezos (I am putting 2 into my first CBG in a week or so) but your circuit looks correct ----- if your wiring is correct and the pot is working your circuit should work. Are you sure you have the jack wired correctly ? Also unclear as to what you are plugging this into - should be plugged into a high impedance input or the signal could become attenuated.

I ended up re-wiring in series (like I have done in the past as well) and it worked just fine.  I only re-wired the piezos, but left all other connections.  My sound is loud and proud.  I still don't know what went wrong this time.  

A little tip to add into the wiring and maybe save some confusion, piezo output is AC , so there is no + or - , same as a single coil pickup.
