Thumbwheel potentiometer guitar Quantitative classification            

Single-connection type: A rotating shaft only controls a thumbwheel potentiometer guitar.            

Duplex: Two potentiometers are controlled by the same rotating axis. They are mainly used in two channels and can control two channels at the same time.            

Classification of Resistance Variation Scales            

Linear Scale Formula: The change of resistance value is linear with rotation angle or moving distance. This potentiometer is called B-type potentiometer.            

Logarithmic scale: The change of resistance value is logarithmic to rotation angle or moving distance. This potentiometer is mainly used for volume control. Among them, the A-type potentiometer is commonly used, which is suitable for situations where the clockwise direction is large and the counterclockwise direction is small. In addition, there is a C-type potentiometer whose logarithmic scale change direction is opposite.            

Thumbwheel potentiometer guitar Classification by material of resistors            

Potentiometers can be divided into two categories: wire-wound potentiometers and non-wire-wound potentiometers according to the material of resistors. Wire-wound potentiometers can also be divided into general-purpose wire-wound potentiometers, precision wire-wound potentiometers, high-power wire-wound potentiometers and pre-adjustable wire-wound potentiometers. Non-wire wound potentiometer can be divided into solid potentiometer and membrane potentiometer. Solid potentiometers include organic synthetic solid potentiometers, inorganic synthetic solid potentiometers and conductive plastic potentiometers. Membrane potentiometer can be divided into carbon film potentiometer and metal film potentiometer.            

Classification by regulation            

Potentiometers can be divided into rotary potentiometers, push-pull potentiometers, direct-sliding potentiometers and other types according to their regulation modes.
