This reasonably matches the way your ears respond to volume. (i.e., doubling the signal amplitude does *not* sound twice as loud to your ears. it takes an exponential amplitude increase to sound like a linear volume increase to you.) Linear pots tend to sound like all the volume change happens right in the beginning of the range, then you hardly hear any change through the rest of the range of the pot. They do not sound like a steady volume increase, which is why the other sort was invented. So volume pots are usually audio/log, expression pedal and such are usually linear. kim ______________________________________________________________________ Kim Flint | Looper's Delight kflint@annihilist.com | http://www.annihilist.com/loop/loop.html http://www.annihilist.com/ |
