    I just bought an OLP MM3 5 string last night (great bass for the money), and just noticed a problem. When I stand more than 10 feet away from my amp, I get a ton of noise. What would cause this?? This is the only bass that it happens on.
    It really isn't that big of a deal. I got the bass just to bring to work and practice. But I would like to know what causes this problem. Thanks for any help.
     
  2. bad input jack.

    If it was a bad input jack, wouldn't the noise be a constant, or just come on when I move the jack a certain way? It's silent until I get a certain distance away from the amp, then it gets noisey. How exactly would a bad jack be the culprit? Thanks.

    Is the cord becoming taut when you get that far away?

    If you move the amp to where you stand (when 10 feet away), then go stand where the amp was, does it still do it?

    I think I figured it out. It's not the jack. I tried moving the cord around at the imput and nothing happens. There's also no pull on the cord at that distance.
    Would my computer cause this problem? It seems to happen only when the bass is near the monitor. Ok, think that's definitely the problem. I guess the pickup picks up noise from the monitor? When I turn off the volume on the bass, the noise goes away.

    Oh yes definitely. Monitors spew noise like crazy, up close. Even a well-shielded bass with humbucking pickups is going to get noise right in front of a monitor.
     
  7. yeah, that pisses me off to. ill try to record something with my cpu, but i have to put my amp and bass far away, so it never sounds clean. meh, damn the computer. WAIT, what if i unplug the screen??~?? wait...then id have to, aline the mouse up, unplug the screen, hit record, memorize where the stop button was, and if i messed up, this could become tireding...hmm...the fixer = get a 4 track ^_^.

    This bass has the MM style pickup with a volume pot for each of the 2 pole positions. When the volumes of both are even, there is no noise when by the monitor. But if I turn just one of them a little bit away from the other, the noise comes back. Why is that?

    The two coils in the pickup (not two "pole positions" :) ) are wired in a hum-cancelling arrangement. When they are both on equally, hum picked up by one cancels the hum picked up by the other. This is how humbucking pickups work, and is also generally how basses with two single-coil pickups (like the Jazz) are wired.

    Ahh...ok, thanks.

    I knew "pole positions" sounded weird. :)
    That sure was a great game though. :D

    I own that game. Really. the real arcade version is in my room. It is fun. I remember playing it all the time when I was younger at pizza hut!
