I own a Washburn AB-20 acoustic bass (AB-acoustic bass-cleaver, huh?) that needs to have the input jack replaced. This is not the standard type jack we all have in our basses and guitars. It makes a bad static noise when the cable is moved. I have not been able to find a replacement jack and the guy who works on my instruments could not help. Anyone have any ideas? This bass also has an XLR input. Could the square input jack be replaced with a standard type? I tried to attach images of the bass and the jack but was not able to figure out how to attach the images of the bass and the jack.
