Hi!
I’m completely new to this, but I found a diagram from the 80s for a fuzz pedal and I figured this was a perfect opportunity to finally learn electronics. I just had a couple questions, which I’m sure are obvious, but I really appreciate any help. Most importantly, the pedal calls for a DPDT footswitch but I can’t seem to find where on the diagram it belongs. I’m also wonder what I need to do to change this from requiring a 9v battery to a 9v dc jack instead. Thanks for your help!!

Your pic doesn't show the complete article. What's shown doesn't need a DPDT switch.
SW1 could be part of a standard 3.5mm switched jack socket as commonly used for plug-in earphones/headphones/ low-voltage supplies.
Normally a DPDT switch (or even TPDT) is used regardless.
Input to centre of one pole, output to centre of the other - join one side of the input switch to the input of the circuit, and the same side of the output switch to the output of the circuit. Connect the unused two contacts together.
This means the circuit is entirely disconnected (other than ground, which doesn't matter) when it's switched out.
