Need help figuring out how to solve the humming sound produced on my accoustic w/ Fishman IV when connected to amp.  I know something is loose on the endpin jack.  I tried different cables and different amps but same issue.

When the cable is plugged-in, it is tight.  But when I press it and keep holding on it, the humming disappears.  What could be wrong, should I resolder the endpin jack, replace the endpin jack?  I need advise what should I do first.

I appreciate hearing any advice or suggestions.  UncRob?

Thank you.

Start by pulling the end pin out.Some factory installed end pins have heat shrink covering the wire and you will need to cut it off...BE CAREFUL you don't want to cut the wire.Inspect the solder joints sometime's there's garbage that slips in under the wrap.If everything looks good solder wize I will just replace the jack as they do go bad.Plug it in before reinstalling to make sure the problem is gone.Again make sure its a tight fit when you reinstall the jack through the hole.As always Call/PM/email if I can be of any help.

Soldering tip:before attaching the wire to the lug tin the wire.By this I mean that the exsposed wire should have solder on it and also tin the lug,I take a lite sandpaper to it so that the solder will adhear.By doing this all you should need to do is press the wire to the lug and a quike hit with the soldering pen will attach wire to lug without melting the wire coating.

Also always use a solder pen,about 40 watts is as strong as you should use.DON'T EVER USE A SOLDERING GUN as they get too hot and will damage the wire.
