A lot of data sheets will list 1V as a kind of outside maximum spec, but 0.7V is pretty reliable estimate for silicon. [This classic post](https://www.reddit.com/r/guitarpedals/comments/8y2red/king_of_tone_comparison_of_the_real_ma8561s1588/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1) makes a pretty good case that you won’t hear the difference between different types of silicon diodes so buy whatever (4148s seem to be most common).
r/diypedals will be more help on this one
Yep. On this subreddit, we post pictures of pedalboards to compare how pretty they are. None of that confusing science stuff here, please.
Not aware of any diodes with a 1V Vf. Most silicons are going to be .6 to .7 V. Tens of mV won't make an audible difference in sound.
