To recap this was the finished product (without all the knobs fitted just for testing in case I had to take it apart again)....
Before I could test the pedal I had a very big challenge to overcome. I didn't have a guitar. Originally I planned to finish this pedal much sooner and ask someone who had a guitar to test it out, but I ran out of time. So putting some of my electronics skills to test (actually it was super easy) I put together a couple of 3.5mm to 6.5mm audio adapters. The idea with these was that they would connect my Mac's speaker output (3.5mm) to the pedal input (6.5mm), then from the pedal output (6.5mm) to my Bowers and Wilkins MM-1 speakers aux input (3.5mm). I had to use a couple of 3.5mm male-to-male speaker cables in conjunction with these to get it all wired up.
Below are some photos of putting these adapters together. They are both mono, nothing too fancy going on there.
Here's a short video of putting these adapters together...
After I had the adapters ready, I launched Garage Band on my Mac and put an acoustic guitar loop on repeat. This made sense to me because I'd be using the pedal to add the distortion/fuzz to the sound. Below is a video of testing out different settings on the pedal. I think it worked pretty well and gave me a good idea of what the pedal was capable of. Of course I expect it would sound much better on a real guitar and I'll wait for my friend Ilia Rogatchevski to confirm it since the pedal was made specifically for him.
