Here is a repost of the images. I changed image hosting sites due to multiple issues.
Below is a photo of the top of the pedal.
Below is a gutshot.
Below is the basic circuit, although I used slightly different input cap values and a 1M pot for the boost control as it was what I had laying around (would have used a 500K instead). Also I later changed out the transistor from an approximately 180 HFE 2N3904 to a similar gain S9013 because the 3904’s I tried I found radio interference in the background when I cranked things up. The S9013 and other transistors I tried didn’t have the radio interference for some reason. The PNP transistor in the original positive grounded circuit was 2N4081 that had gains around 90-330 HFE, so anything in that range should work.
