I'm following Lorenzo's layout (http://www.musicfromouterspace.com/analogsynth/YOUR_FIRST_SYNTH/lor_wsgpartslayout.GIF) to some extent, except that I am using perfboard and housing it in a boring Rat Shack case.

I just have a quick question about the three leads on pots: Does it make a difference which of the outside leads are "A" and "C" (or "1" and "3")? In the layout I'm following, most of the pots have wires connected from an outside and middle lead to a component, and the remaining outside lead is either ground or another component. Does it matter which outside lead is wired with the middle lead, as long as it is going to the correct component?

I guess what I'm saying is that I can't identify any "A, B or C" on the pots, and I'm not sure towards which side 0 or 10 would be (like on a volume or EQ knob, for example).

I'm probably overthinking this, but as I am not using the same pots that Lorenzo used and not laying them out the same way, you can see how I could possibly get confused.

This is my first soldering job, and I only burned myself once! YES!

If you get these terminal backwards, it will still work, but the knob will work backwards. Usually it's easy to change.

Thanks for replying. I found a decent website that explained the wiper terminal and basically confirmed the same thing you had said.

I guess when it came time to drill the holes in the case for the pots, I freaked out when I was thinking about which direction the terminals would be facing (relative to the front of the perfboard, where the toggle switches and 1/4" jack are).
