So I just got a used bass and small fender amp. The only problem is, the input jack on the amp is broken. The jack seems Fender specific; it's housed in a sort of rectangular plastic case with four contacts on the bottom that fit into the circuit board. I think I could fix it just fine if I could find an input jack just like it, but I can't find one anywhere. Does anyone know where I can find such a thing? If not, does anyone know how I could fudge it with some other type of input jack? Thanks a ton!

Try Mouser or Digikey.
