AG is correct, and I answered that post explaining the industry standard reason for the "B" connection scheme. ButI am used to having my advice ignored and then guilty of saying "I told you so."the original post asked about connecting the wiper to one end of the pot.
The world of audio amplification is well on my low end of understanding. That said - the reason for the post is to show the TS what I consider the correct way to wire up a pot. Even though both ways (A & B) are done. In fact, my variable regulator has the "A" configuration.Tony, your opamp has a gain control from 1 to typically 200,000 times.
Its 0.1uF input resistor feeding the low value 10k resistor cuts 800Hz a little, cuts 160Hz at -3dB and cuts lower frequencies at -6dB per octave.
