Description Catfish A500K Large Logarithmic Potentiometer with split shaft large housing.Economy version, with corrugated axle Made by Alpha in Korea. A 500K logarithmic (also known as audio taper) potentiometer is commonly used in electric guitars for volume and tone control. At volume the logarithmic potentiometer changes its resistance in a way that matches the human ear’s perception of sound, so this kind of potentiometer offers a smoother and more natural volume adjustment. The A500K potentiometer is frequently used as a volume control. The logarithmic curve allows for smoother, more gradual volume changes, which is especially important for performing musicians who need precise control A 500K potentiometer is commonly used with humbucker pickups, which have a higher output than single-coil pickups. The higher resistance allows more of the treble frequencies to pass through, preventing the guitar from sounding too dark or muddy. 500 KOhm Logarithmic is Also Known as Audio Pot Large Housing 25 mm x 31 mm
