    Greetings,
    I am looking for help with a Warwick Corvette STD 2008 passive 5 string
    Just a couple of weeks ago a strange hum noise like a single coil hum started happening. Now it is so bad that it will cause feed back when any amp is at higher volumes, band playing volumes.

    The hum goes away when then tone is rolled off all the way. Looked at the electronics and nothing appears visually out of place. Physically all the connections are fine.
    The hum noise is there for all three neck, both or bridge pick up selections (single coil Jazz type).

    I was thinking a grounding issue but that usually goes away if you touch the strings or the wires inside the cavity but the noise is still there. Rolling off the tone you can hear the noise lessen the more bass it gets and less treble. Both pickups are just as responsive and loud as ever. No noticeable difference with either pickup.

    I do not think this is any interference unless the pickups have failed for some reason.
    Anyone got an idea or have experienced this before?

    I had posted this in Pickup section before and moved it here

    Any thoughts would be very helpful, thanks

    When you roll off the tone, the only thing that changes is the relative amount of current going through the cap versus the tone pot. One of those two is having problems, I suspect your cap either took a dump or isn't soldered well.

    Ah, the capacitor
    maybe the cold weather we have been having has caused a failure in the cap area
    there is a very small 'pill' shaped cap on the tone pot
    Thanks I did not think of that :)

    Did that solve it? Did you have to replace the cap? I have the same bass, a year newer, same noise...
