a linear potentimeter turned to the half way point of it's rotation will be half of it's total resistance.
an audio(log) potentiometer will not. the majority of it's resistance is at the end of it's taper. if it is 10 to 20% of it's total resistance at it's halfay point then it is a standard audio(log) pot. if it is 80 to 90% at it's halfway point then it is a reverse audio(log)pot.
lefty's might want to use the reverse audio(log) potentiometer, but i am not a lefty so have never tried it.
if you swap the potentiometer out for a linear pot. most of the volume will come before or about the halfway point and you will witness very little difference from there.
here is an article link. geofx's article with is very informative and explains it very well.http://www.generalguitargadgets.com/ind ... &Itemid=44http://www.geofex.com/Article_Folders/p ... tscret.htm
