Guitar potentiometers are very important pieces of electronics that make it easy to change the volume or tonal characteristics of the output signal. At its core, a guitar potentiometer is a variable resistor.
This makes it possible to partially cut the signal coming out of the guitar: in the case of the volume knob, the signal as a whole is "cut off", in the case of the tone knob - only high frequencies. The resistance level is regulated by the musician himself - there is a conventional scale from 0 to 10 on the potentiometer knobs.
