Broken Input Jack

    The problem just suddenly happened a few days ago without warning! :spit:
    Whenever I plug my bass into an amp, there is no output, or at least there is the teeniest tiniest amount when I turn everything on my amp all the way up!
    I've checked if it's either the amp, the battery or the lead by plugging into different things and I'm pretty sure it's the bass that's the problem.

    I've opened it up to have a look, but it doesn't look like there's anything wrong with it... Then again, I'm a bit of a noob at the moment with this sort of stuff.

    I can't upload pictures at this time, but any thoughts on what the problem might be would be greatly appreciated.

    It's a green Yamaha RBX765A if that helps at all. I think it's an enclosed jack,

    Thanks for reading,

    Sorry, forgot to mention that! Yes, it's active, a single 9 volt battery. It's not the battery either... I did the licking test to be sure!

    The "licking test" is not enough. Even a battery with much less than 9 volts will still give you a jolt on your tongue, but NOT have enough voltage to power your pickups. You should definitely try a new battery. That could very well solve the problem. And don't get a cheap battery, either.

    licking test, I like that :D

    Yes, licking test isn't accurate and a new battery would eliminate all the doubts (Those are not active pups, btw).

    Yeah, no surprise if the jack was broken, those things are crap.

    Just these last few weeks I had three customers coming in with the same problem. I modified the instruments with traditional switchcraft jack and football plate…

    BTW, it's an OUTput jack, not an input. The terminology is important because it helps you understand troubleshooting. The signal goes OUT of the bass.

    First thing to check on an active instrument is the battery. As suggested above, go out and buy a new, good alkaline battery and install it.

    Also check the jack with a plug in it. Look closely to make sure there is good contact at each point.

    If it's a common Yamaha bass, testing the contacts with a plug won't be easy as they all use barrel jacks.

    Ahhh... Thanks for the corrections on terminology as well, I'm not very good with this area of bass at the moment :)

    Well, I tried a new battery and it hasn't worked. What could it be now? I'm presuming it is a barrel jack, are they the same thing as an enclosed jack?

    yes. My suggestion, find some one who would install a standard switchcraft and the football plate. You'll spend a little more, but it will last 10 times longer

    What does football have to do with it?

    Just kidding... But does that mean I'll have to replace the output jack (?)

    Meh, that's not what I expected the outcome of all of this to be, but if this will make it work then that's fine by me!

    Thank you for the help! :)

    well you can just replace the barrel jack (which will be a little cheaper), but expect to fail sooner than a "traditional" jack.

    No biggie, just my experience/suggestion :smug:

    Cool, so an open jack like the one above would be more reliable than an enclosed/barrel jack?

    How much do you think it would cost to get this sort of thing done by a professional or by myself? :)

    barrel jack $10-$12 (+ event ship.)
    Switchcraft jack and plate ~12 (+ even ship.)

    Installing the switchcraft jack implies enlarging the mounting whole, not at all of a problem.

    Average costs:

    Barrel ~$40
    SC ~$55

    Wait... Does a barrel cost $10 or $40? Sorry, I was a bit lost there.

    Oh wait, I get it! Would that be the cost of doing it by myself or getting a professional to do it? :)

    My friend got the plate and jack for 0.5$ and it's been working flawlessly for years. Never got my mind around why people buy such expensive jacks and plates.
