Audio taper volume pot issue

[bhuether]

I just installed a CTS audio taper 500K volume pot. I also put a .001 uF capacitor between input and output terminals. The volume control now has most of its effect in a small portion of the knob (towards the lower volume part). Not sure if the capacitor is effecting that.

Also, the cap seems to leave too much highs in. I tend to like a mellower sound when the volume knob is lowered. Any capacitor values you recommend and also what do you make of the audio taper issue? IU mean I realize that audio taper is non linear but I thought across that nonlinear curve you are supposed to hear a continual change in volume (i.e. the ears process the nonlinear change as linear).

thanks,

There are (at least) two solutions. Put a resistor in series with the cap (100k-470k) to reduce it's effect or just change to a smaller cap. I find that I like a 120pf cap there. It leaves just enough sparkle without dominating the control of the volume pot.

A resistor in parallel with the cap can help to change things up as well. Give them a shot.

Wire a 220K resistor in parallel with the cap. It will smooth out the taper of the pot and somewhat ease the high-pass ability.
