    Just had an Eminence Private Jack loaded into my Fender Musicmaster combo. Everything seems to be working as it should but, now there is a high-pitched humming sound that is present. Gets louder as the amp is turned up, is present even with the guitar unplugged.
    Could a cold solder joint on the speaker terminal be the culprit? Or am I looking for something else?

    Also, the 50w Private Jack seems to be breaking up a little more than the 20w alnico organ speaker I just removed, that doesn't seem kosher to me.

    Did you plug your old one back in, and it is still ok?

    I haven't yet. The speaker is soldered in & I'm not the best at that game just yet. I have tools to solder but none for removing soldering unfortunately.

    Melt solder. Pull off wire with pliers. No other tools or skills required.

    To my original point though, would/could a bad solder job cause this sort of high frequency humming?

    You can test your solder joints on the speakers by tapping/whacking them with a pencil or chopstick when the amp is on. DO NOT USE ANYTHING METAL TO TAP THEM.

    If they aren't the best, you'll probably notice a sound change when you tap the connections.
