He uses his pinkie finger to flip the volume on and off for dramatic, lightning-fast starts and stops.That’s why Yngwie’s YJM High-Speed Volume Potentiometer contains a minimal-viscosity lubricant for fast-action potentiometer turns. At its core, the YJM High-Speed Volume Pot is a high-quality 250k. or 500k. Bourns potentiometer customized for Yngwie.s playing needs. The split-shaft design of the post can accommodate a variety of knobs.This is the 500k Ohm version, and is best used with humbuckers or high output single coils.Comes with mounting hardware.
