YJM Signature Potentiometer with 250 kOhm from Seymour Duncan.
The YJM High-Speed Volume potentiometer was developed by Seymour Duncan together with Yngwie J Malmsteen. It is filled with a low viscosity lubricant, making it very easy to use. This suits Yngwie's playing technique, as he often fades the sound in and out with the volume potentiometer to achieve a higher dynamic in his phrasings.
