So I just got my new bass, my make an NGD later.. Thing is, when I push the lead into the jack it doesn't work. However, it works when I put it in halfway. It works fine, but its kind of weird, will it be okay like this?

And also a knob or two is loose, is there a chance of it not working?

Easiest thing to do here is to take it to the local tech or luithier and get them to sort out these problems. It costs money but it will get done and then it will be fine.

Or if you bought it from a shop return it and get them to fix it for free.

Oops sorry, the lead was just my stupidity. Just one of the knobs are loose.. How to tighten?

If it has a grub screw just tighten that, otherwise the inside grip might be worn away and youll have to replace it, or stick some paper in their.
