    Hey guys, i recently purchased a cheap 5 strings for fun. But it looks like it might have an issue

    When i put cable to jack input its kind of hard to do.. you may need to push it a bit in the first place but will get better afterwards

    however it sucks throws back.. kind of vomiting my cable -_-

    when i touch it or try to move it a bit it simply pushes it back immediately.

    Its an active 5 strings if its going to help.. ermm Harley Benton HBZ- 2005 i think

    Edit:

    The question is what to do ? what can be problem ?

    I dont have tools with me to check it out.. Not until next weekend

    Sounds like something is wrong with the jack. Replacing the jack is easiest fix.

    Active usually means one of those cursed barrel jacks. All you can do it replace it.

    Replace the jack. Anything else is just a waste of time.

    if it's a barrel jack, the replacement will be a switchcraft #152B.

    You'll have to bore out the hole to accommodate a normal jack, and add a metal, "football", to mount the jack. *OR*--do what I did, and go with an electrosocket.

    On an active bass the jack also switches the active electronics. So you'll have to replace it by a switching (3-pole) jack.

    Sounds like the inner clips are bent. It's a barrel jack. I hate those, even the Switchcraft one. First choice is to replace it with a Switchcraft one, but buy a couple because they all tend to get unreliable. Second choice it to drill out a larger hole as JLS says. Not really hard if you're used to using power tools on good wood and aren't squeamish. That also assumes you know about soldering guitar circuits.

    And if you go to an electronics place asking for a switching jack they may not understand what you're after. You want a TRS ("tip, ring, sleeve") 3 conductor 1/4" jack. The tip connection is the hot from the bass's audio output. The sleeve is the standard ground. The ring is the connection to the power side of the circuit. When it shorts to the barrel of a regular mono T/S plug (jacks are female, plugs are male), it completes the circuit and allows power to flow to the preamp.

  12. No, you don't need a switching jack for this but you will need a stereo (TRS) jack which is probably what's in there now.

    A rubber band, keeping the jack in place, might help you out for the time being.

    That's why I wrote 3-pole, between brackets. It switches by shorting two contacts with the mono jack, which you apparently knew already.
     
  15. A switching jack has a switch in it. A TRS jack does not. They are not the same thing.

    are you using a straight-out cable?

    if so, that's the problem, and what has likely worn out the jack.

    use a 90° jack on the bass, threading it through the strap; that'll way reduce the sideways stresses placed on the jack and the plug (and the cable itself).
