The idea of a linear tape is so that the difference between each setting on the volume knob, it it has numbers on it, is more gradual, wheras an audio taper can go from soft to loud tooquickly and for some,it can be extremely difficultto get a desired setting. The exception to this rule I can find very quickly is the difference in the tone pot and volume pot settings that are used on 4-10 Bassman amps, and the real deal used the audio taper, which actually had many more useful setting inbetween the numbers wheras the linear taper pot does not. Again, as a VC for a microphone, a linear taper is a lot easier to work with. So in essance, it has (for the VC of a microphone) little to do with what you hear, but how you're able to set things up more than anything else.
I use linear taper pots in general and find their response to be smooth and linear. Yes, I understand that with audio, an audio taper should be linear and a linear taper should not - but experience says linear works just fine. There are also pragmatics involved. I go through a lot of pots, but the ones I use are not stocked in an audio taper and to get the would require me to purchase a minimum of 10,000. Ain't gonna happen.
Look, guys, there's theory, and there's practice. In theory, we should all be using audio taper pots. In practice, linear taper pots work just fine for microphone volume controls. I've sold THOUSANDS of microphone volume controls. Hi impedance, low impedance, extra hi-impedance, in-line, built-in, you name it.The volume response of my controls is very smooth and fairly linear, TO THE EAR, across the entire rotational range of the knob. Properly matching the value of the pot to the element IS important.I have NEVER had a complaint about non-linearity and I'm sure there are owners here of my stuff who will back me up on this.
Harpaholic - which manufacturer are you referring to and where do you get the pots?
