I just built an OD-808 last night for fun (you can never have too many tube screamers
).
Some notes - the vero from this site has the series 100K, 1 uF which appear on the input buffer (see below). These are unnecessary and can be removed (not sure why they showed up in the schematic). With the space you now have, you can add a 1M antipop resistor at the input, next to the 1K resistor.
Although I soldered some clipping diodes in for now, I'm going to remove them and set up some sockets for experimenting with clipping options. Should be fun.
