Hello ,
i'm a newbie. I just upgraded my pot from alps 100k (radio shack) to 50k alps black pot and I noticed that the sound got louder. Should I switch back to a 100k pot to better control the volume? Curious, how much volume can a 100k vs 50k pot lower by? or can i add a 10k resistor to the 50k pot to lower the volume? any comments?
thanks

If the original pot was logarithmic taper (most likely), and the pot you used to replace it is linear taper, then new pot will be louder at settings below full volume. Log taper varies the volume by increasingly larger amounts to compensate for the way our ears hear volume changes.

If it's a 50k linear, use Rod Elliott's law-faked volume control by adding a 7.5K resistor to ground. See the details at Rod's site.

I see where you are coming from as the diagram is a bit misleading as the arrows appear to point the opposite way. Reverse the arrow directions and that's the signal direction.
If you look at the pot from the front (shaft pointing towards you), the first connector on the left is #1, centre #2, right #3.
#1 is ground
#2 is output
#3 is input

Resistor goes from #2 (output) to ground. This only works for a linear (B) pot and not a log (A) pot. Was a lot easier when a manufacturer included that info in the part number such as AX2 would be a dual gang log pot and a BX2 would be a dual gang linear pot.
Hope this clears it up for you.
