Xotic Silent Knob [Flat Top] Two new, unopened knobs. Eliminates touch noise when using distortion. Will be shipped via Nekopos. Thank you. [From the official website] Conventional metal knobs can produce a popping noise when touched due to static electricity caused by contact with the metal shaft of the potentiometer. The Silent Knob uses a durable insulator (Delrin) with little aging inside the knob to completely shield the potentiometer, completely eliminating troublesome noise. ■ Uses a 2mm hex wrench to secure the shaft ■ Flat Top Chrome 1 piece ■ Brass sleeves cannot be used ■ For 6.35mm inch solid shafts (round rod shafts). - Model: XP-SK2 Silent Knob (Flat Top) - Color: Silver fender Telecaster PB Precision Bass Pre-B OPB conductive paint
