Mod Electronics Oil Caps are meticulously crafted, superior capacitors renowned for their exceptional performance in a variety of applications, including guitars, amplifiers, and audio equipment. These capacitors are meticulously manufactured, undergoing a meticulous process to ensure their premium quality. Each capacitor is infused with mineral oil, guaranteeing a void-free winding that contributes to remarkably stable capacitance. Moreover, the capacitor is hermetically sealed within an aluminum casing, enhancing its durability and longevity. The .033uF guitar tone capacitor is for those seeking a middle ground between the .022uF and .047uF capacitors. Whilst the .022uF is great for humbuckers and the .047uF perfect for single-coils the .033uF sits just in between, great if you have slightly darker sounding single coils or a bright humbucker.
