Commonly used as the Volume control in Jazzmasters although some Strat players also prefer this value and taper. How does a linear taper pot differ from an audio taper pot? With a linear taper the resistance changes evenly with the degree of rotation; at one quarter rotation the pot should read around 250K ohms, at half rotation the pot should read around 500K ohms etc. An audio taper pot changes very gradually; the ohms read pretty low until you start getting into the last 15% or so of rotation and then it increases very rapidly.
