    Hi folks,

    I've got a Fender Aerodyne and an Ampeg B2RE. With the tone knob at anything other than 0, I get noise from my head and associated cabinet (a 4x10 Genz Benz). This noise is not present when I plug my amp into an audio interface or a 15W combo speaker.

    How can I troubleshoot my head to figure out what the issue is? Is this the case of a bad ground?

    Thanks

    Try standing/sitting farther from the amp.
    Try turning your bass to different orientations with respect to North/South & East/West.

    Here at home, If I point my instrument to the South or North, I get no interference, but as I rotate it towards the East or West, the interference gradually gets louder.

    If not the amp or bass, must be the cab. Blown tweeter?

    I had this issue with my Fender Tele bass. It happened with all my amps so I knew it was the guitar. You say it doesn't happen when you plug your amp into an audio interface...etc, did you mean "guitar"? I thought my guitar needed new pots, but the tech replaced the input jack and it solved the problem.
