Just always remember, every potentiometer, toggle, and rotary always go on the opposite side of the components.
The few exceptions are trim pots and some slide toggles. That is because it makes for "easy" access when opening the back of the pedal to tweak parameters. In a few cases, I wire a potentiometer to the trim pot spot, so I am able to actively control the parameters from the top of the pedal with the other potentiometers.
Definitely dig the Mystery Machine. I use it for mostly low gain drive/distortion. Personally haven't found a good transistor to use for the "heavier" distortion/fuzz side. Probably because I'm still struggling with fuzz since Overdrive is my jam.
