Link - Fc22714057

FC22 is a part number for a Fender amp, like the Fender Champion 22. But FC22714057 seems different. The format FC-2271 might be a part number, maybe for a specific component. The "4057" part could refer to a specific chip or resistor. The 4057 is a common CMOS analog switch IC. So maybe FC-2271 is a part in that family. The link could be a datasheet or product page for that component.
