distortion from onboard electronics?

    I'm getting a crazy amount of distortion from my bass (yes I'm pretty sure its from the bass) and I'm suspecting its from the oneboard electronics. Can someone help me with this? any advice would be appreciated, and yes, I have already tired to replace the battery.
     
  2. Have you tried turning down the pre-gain or padding the input (hitting the active button)

    It could be you are clipping the input on your amp, or you could be trying to push too much bass into the signal

    what is padding the input? I'm also not sure what you mean by pregain, but if you mean the pregain on my amp, there is distortion no matter how low I turn down the gain. my bass boost/cut knob on the bass is turned to neutral. So I'm not sure if I'm pushing to much bass into my signal. also, there's know clipping going on (the clip LED isn't activating)
     
  4. the pad is the active/passive input (some amps have different inputs, some have a button)

    is it a combo or a half stack amp you are using?

    what makes you so sure its the bass?

    Can you give some more details? What kind of bass and what kinds of pickups, preamp etc.?

    Did this just start?

    Does your amp have a high and low (or active passive) input?

    Does it clip even with the bass volume turned down?

    I had something like this happen once and it was a bad ground connection on the output jack of the bass.
     
  6. People need to read posts already done!

    It doesnt seem to be clipping as it happens at low levels and with bass on the center detend, ive brought up the active passive input thing also

    I'm using a schecter 4-string bass

    the amp is a stack, the head is SWR Workingman's 2004, the cab is 4x10 hartke. There are seperate inputs for active and passive, I'm using the active one.
     
  8. Have you confirmed that it is definitely the bass? If possible, try another amp/rig and lead. You might want to try a third battery, its unlikely but it would be handy if you'd just put the one-in-a-million dud. Also, have look inside the cavity for anything thats obviously out of place, loose solder joints, the such.

    By crazy distortion, what exactly do you mean? Is it similar to dying battery, distortion on hard transients type of distortion? Or I'm a crappy connection, 'bang snaple crack bang' type distortion?

    I'm a little lost for ideas, based on what you've said so far, so the best bet is eliminating incorrect ideas until the real one becomes evident.

    I did read the posts, and he didn't answer any of my questions. Why don't you read what I asked and then re-read his post.

    Read what I wrote in my question... I can see it's not the amp clipping. You mentioned an "active button" ... many amps have separate inputs.

    And did your post solve any problems? :rolleyes:

    OK, now I asked you if the distortion is still there with the volume control on the bass turned down? Does it change the amount of distortion? This would determine if the distortion is originating in the bass itself. If you get the same distortion with the volume down (on the bass, not the amp) then it's not clipping your amp.

    It sounds like the bass to me, and not the amp.

    Also, is the plug snapped all the way into the jack? Sounds like a silly question, but if the plug is acting up on an active bass you can get a lot of distortion (has to do with the ground and the battery). I've had this happen to me a few times. I ended up replacing the jack.

    Also did this just start happening? Have you changed anything? Could be a problem with the bass' preamp.

    I'm asking standard trouble shooting questions... :D

    How intelligent.

    And you solved his problem how exactly?

    You made a bunch of assumptions about things he didn't say.

    I was asking him some questions, so either contribute something constructive or keep quiet.

  13. Intelligent it is, seeing you were contradicting your point, oh, theres a big word for an american

    I asked a few questions, many of which were unanswered and could easily have been the problem

    You told him to; 1) "turn down the pre-gain or padding the input (hitting the active button)"

    Pre-gain? Care to explain what that is? If you are referring to the the volume on the bass, that's not "pre-gain"... it's not even gain. If you are referring to the gain on the amp, that's not "pre-gain" either... it's gain. Preamp gain? Learn proper terminology... it's not pre anything.

    So that's not helpful at all, is it? He didn't know what you meant either, because there is no pre-gain.

    Also if he thinks it's the bass, I'm sure he tried changing the settings on his amp. Because he wrote:

    "also, there's no clipping going on (the clip LED isn't activating)"

    So it's obviously not the amp.

    Then you said: "what makes you so sure its the bass?"

    Ummm, no clipping light?

    Then you wrote:

    "It doesnt seem to be clipping as it happens at low levels and with bass on the center detend, ive brought up the active passive input thing also"

    The word is "detent" not "detend" As an American I also know how to spell. ;) He said nothing about low levels... he only said the bass EQ knob was set flat. That's why I said you made assumptions.

    So nothing was answered. I also mentioned the high or low input just in case he didn't know what padding was. And he didn't.

    So learn what you are talking about before you attempt to help someone, and don't have an attitude when someone tries to correct you.

    I have a background in electronics and have been building guitars since 1974... what are your credentials? :rollno:
