(set of 2) Hand-soldered here in my Houston Texas shop! 220 K Ohm 1/4 WATT 5% Carbon Film Resistor & 471pf capacitor. Great popular MOD used on many single coil guitars. Wire this simple mod between the input and output lugs of your guitar volume control pot, to smooth out treble bleed. Get more uniform tone from 1 to 10, and a more rounded sound at low volume
