CTS 'USA spec' Precision Linear Taper Potentiometer.The CTS precision linear taper gives you smoother and more accurate response than with economy pots. They feature longer life brass shafts and much tighter resistance tolerance. Linear taper pots can be used for tone controls.Specs: - USA spec thread: 3/8" x 32.- 3/8" (9.5mm) diameter brass threaded collar.- 24 spline (fine) brass split shaft.- Includes 1 x nut, 1 x dress washer and 1 x lock washer.Dimensions:- The brass threaded collar is 12.5mm long.- Total length of the shaft to the top of the spline is 22.2mm.- Split shaft diameter : 6mm.- Pot casing diameter : 24mm. Which Ohm value should you choose?500k pots are the standard volume and tone controls for humbuckers, and 250k's are usually used for single-coil pickups. A 250k gives a slightly warmer tone than a 500K by sending more of the high-frequencies in the circuit to ground.
