Very noisy 1968 jazz pickups

[Thebassman75]

Hi

I have a 1968 jazz and the pickups have developed a problem. Whenever I touch the pickup casing, say if I'm resting my thumb on the back pick-up as an anchor, there is a very loud noise. The noise is similar to the noise you would get if you ran your finger across a microphone. So, logical theory suggests that the pick-ups have become microphonic. The issue is, how do I sold this? I've had the pick-ups out and all of the original shielding is in place so I don't think that's the issue. Could it be that the pickups need wax-potting or is there something else I could do that wouldn't change the original state of the pickups? It happens on both but there is no earth hum or any other noises..

Thanks in advance..

Wax potting will usually solve microphonic pickup problems. Given their age, it's likely the'll need doing anyway.

If the output from them is fine then the windings should be intact (sometimes these corrode). I would have recommended [url="http://www.wizardpickups.co.uk/"]Wizard[/url] pickups, as they have done mine in the past... but as they are no longer, you could try [url="http://www.creamery-pickups.co.uk/guitar-pickup-repairs-and-rewinds.html#.UlupdyQ4SUA"]The Creamery[/url]. I haven't used them so can't recommend, but I hear good things.

Or if you're feeling brave... [url="http://www.premierguitar.com/articles/How_To_Pot_Your_Own_Pickups"]have a go yourself[/url]
Personally, with pickups from a '68 Jazz, I would not be brave enough to have a stab.

I'd be tempted to put them aside and invest in some modern "vintage" replacements - Aguilar humbuckers etc. I've had microphonic J bass pickups potted (Barenuckle) and it reduced the problem a lot, but didn't completley remove it. You can keep the original covers on with most modern replacements, and always go back to them if you feel the need.
