MM SUB input jack

[pbgonecrazy99]

For the longest time my MM SUB has had the problem of the touchy input jack. Whenever I plug in the cable, I have to move it around until I can get some output that isn't screaching. I was wondering if anyone knew how to fix it, and if it is possible to fix it without going into a shop and having it fixed (I have a decent amount of soldering experience).

you should replace the jack.

Probably need a new jack, easy repair if you know how to solder. You could try bending the spring part of the jack to make sure it is making good contact too.

That is what I was thinking about doing, but the jack has a black plastic thing on it, so I don't know if I can get to it.

But I am guessing I need a stereo jack? I am not to sure, need some help.

oh.. also, sometimes a patina builds up in the sleeve portion of the jack, preventing good contact with the plug. if so, it can be cleaned/resurfaced with a corner of a ScotchBrite pad (your wife probably has one under the kitchen sink).

You can also spray some deoxit cleaner on it to clean it all up

I will definitely try that, but it is hard to even see the metal flaps of the jack since the plastic cover of the jack makes it difficult to reach. It is hard to describe what it is. It is like a black cube that spans the input jack.

That style of jack is pure junk. Put a Switchcraft in it and you will be fine for years.

Here is a quick pic I found of the jacks Invalid Link Removed.

The question I still have is that I need a stereo jack since it is active, correct?

Yes.

You can still clean the jack, and with a long narrow tool you can still get at the tip sleeve if it's too loose. Remove the control plate and work on it from both ends.

It's a switching jack. It turns the preamp on when the cable is inserted. I've bought my replacements direct from Musicman.

Ya I am going to give that a go when I get back home. I lifted he control plate once, and was like hellz no I am not touching this. But my bass teacher said it is a common thing that happens to SUBs. Sucks that I waited so long to fix it, could never play live shows with it.
