I'm a rookie myself but I have a few thoughts: 1. D3 is omitted. 2. What value do you have at C16? That cap looks big.
Also, I think the pot for the clock trimmer will be fine for testing, but you won't want to keep it that way. The best way to set these up is to set your clock with a frequency meter and then bias the BBD. You can use your scope to bias the BBD. Here's a post where I learned how to do this on the Current Lover, the procedure is similar but your frequency will be 30-35kHz at the minimum: http://www.madbeanpedals.com/forum/index.php?topic=27581.msg267486#msg267486
You can use your scope to trace the signal all the way through the circuit the same as an audio probe to diagnose any bad parts or cold solder joints. Just put a sine wave into the input jack and follow the signal through each step of the schematic. For the sine wave, I use aa app called Function Generator on my phone and a headphone jack I wired to a 1/4 inch plug.
