Product name:GF 500K lift potentiometer
Manufacturer:Japanese imports(Bihan and Taiwan made Alpha much better)
Range of use:A tone cut used mostly for electric guitars
Sales mode:60 yuan / month
Product performance:The rotation is very smooth, increasing the sensitivity of the adjustment. Reduce output resistance, increase volume and tone output, and extend service life.
Other remarks:Potentiometers are generally B for volume, and A for tone. However, some of the volume and tone of the piano are A, or the volume is A, and the tone is B. In fact, the A and B properties and not what the big difference, the only difference is the A index change, simply means that when the A begins to rotate, the resistance changes greatly, and in the end when the angle is close to the maximum resistance, resistance changes and decreases, so you will feel it is not too uniform change. The B is linear, and the resistance varies substantially with the angle of rotation of the potentiometer. The change is very uniform. Therefore, the choice of A or B, according to their own habits.
