Help with Ruby pot wiring

[suprleed]

I know a lot of you have built the ROG Ruby.  I had a quick question on wiring the gain pot.  I've seen multiple ways of wiring the lugs of the gain pot to pins 1 and 8 of the 386 chip.  For example, The ROG website (http://www.runoffgroove.com/ruby.html) shows lug 3 going to pin 8 and lugs 1 & 2 going to pin 1 of the 386.  Dano's Beavis Audio website (http://www.beavisaudio.com/Projects/NoisyCricket/) shows the opposite, lug 3 of the gain pot going to pin 1 and lugs 1 & 2 going to pin 8 of the 386?  Will both of these wiring schemes work?  Or will one of these actually decrease gain as it is turned clockwise?

Thanks

A pot is two resistors, that add up to the value of the pot. When you turn the shaft, the first resistor is increased (or decreased, depending on the direction of the turn), and the second is decreased (or, again, increased). So basically what happens here is that in ROG's example you increase the resistance between lugs 1 and 8 of the 386, and in BA's example you decrease the resistance simultaneously. It has the exact opposite effect, turn the shaft clockwise, it increases the gain on one but decreases it on the other amp. Looking at the datasheets, I believe the higher the resistance, the higher the gain (from 20 to 200), and if you place a capacitor across the two lugs, the gain is automatically 200. So... On the ROG Ruby the more you turn the gain to the right, the more gain there will be, and on the BA's Cricket there will be less gain to the right... Don't quote me on that, but I highly believe that is correct what I just said.

Thanks for the explanation.  I was wondering about this very thing.  I've read over multiple websites about pots trying to make sense of whether wiring one way vs. the other would increase or decrease gain.  I appreciate your insights; very helpful.
