Potentiometers

A pot is variable resistor. Most common guitar pots have a layer of conductive carbon deposited on a non-conductive phenolic plastic base. A metal "wiper" sweeps along this carbon variable resistance path as the pot shaft is rotated, allowing us to change the resistance and thus choose the level of attenuation. The density pattern of the carbon deposit determines the taper of the pot. A linear taper pot changes resistance evenly; at about half rotation (12 o'clock) you'll get roughly half the total resistance of the pot. An audio (A.K.A. "logarithmic") taper pot works differently; you'll have to turn it up to about three quarters rotation to measure one half of the resistance value of the pot. Try this yourself with an audio taper pot, a linear taper pot and an ohm meter. Looking down at the top of the pot with the solder lugs facing away from you, put your two meter probes on the left-most and center solder lug. Now turn the pot all the way counterclockwise and you should measure the total resistance of the pot (e.g. 500K or so...). Now turn the pot shaft clockwise to about half rotation; it helps to have a pointer type knob on the shaft to keep track of the rotation. If you're measuring a linear taper pot, about half rotation should give you half of the total value of the pot. If you turn this linear taper pot up about three quarters rotation you'll measure 20-25% of the total resistance value. When you turn the pot up all the way clockwise you will probably still measure some resistance, say 2 to 60 or so ohms. Now try to measure an audio pot. You find that the resistance changes only 15-20% or so at half rotation, reading half the total resistance value only after you've reached almost three quarters rotation and then it drops rapidly (logarithmically...). Audio taper pots are commonly used when fine adjustment is needed at lower listening levels. There are many other pot tapers available. In my experience, different examples of even" standard" tapers such as "audio" can vary quite a bit in how they feel to a guitarist. Here again, experimentation with different pots may be worthwhile. Remember that a pot is not an amplifier; it can only attenuate signal.
