Hutton Posted February 7, 2012 Share Posted February 7, 2012 My cherished SUB has started to make a horrible loud hum. I've changed leads. Tried other basses. Put it through another amp. All points to the problem being with the bass. I've changed the battery to no avail. I think that it has possibly something to do with the jack socket as when I wiggle the jack in the socket it can bring on the hum. I was wondering if anyone with a Ray/SUB/other MM bass has experienced this. Quote Link to comment Share on other sites More sharing options...
brensabre79 Posted February 7, 2012 Share Posted February 7, 2012 SOunds like an earth issue. Is it active? Quote Link to comment Share on other sites More sharing options...
Hutton Posted February 7, 2012 Author Share Posted February 7, 2012 Yep. It's active. Is there an obvious place to check for earthing issues? Quote Link to comment Share on other sites More sharing options...
lettsguitars Posted February 7, 2012 Share Posted February 7, 2012 Look for loose earth wires. Joints that wiggle but aren't obviously broken. The outer pin of the jack is where you need to check first as that sounds like the culprit. Quote Link to comment Share on other sites More sharing options...

brensabre79 Posted February 7, 2012 Share Posted February 7, 2012 Yep, open her up and check the wiring, also check the socket - sometimes the pins can get a bit bent and short out/not contact on the stereo jacks. It may be that its earthing through the battery -ve wire or something. Quote Link to comment Share on other sites More sharing options...
bassmachine2112 Posted February 7, 2012 Share Posted February 7, 2012 I,ve had this on my SUB along time ago. Check the solder joints where the pins for the jack attach to the circuit board.The solder was cracked,very hard to spot-remedy-resolder the joints. How to stop it happening-don,t pull your lead tight under the strap ,it puts sideways pressure on the jack and cracks the joints.Keep it loose with a decent bit of length. Hope this helps.

Hutton Posted February 14, 2012 Author Share Posted February 14, 2012 All is now well with my SUB after calling in on Rich (Ou7shined). Rich really knows his stuff and the suspect jack socket was sorted out in no time. However, it was Rich's bass building operation that really impressed. Rich had a couple of basses in mid-build which look as if they are going to be really tasty. There was also a completed bass in the style of a G&L but with Rich's own take on things the bass looks fantastic and plays beautifully. If I am fortunate enough to be able to afford a custom build in the future I know who's going to build it for me! Quote Link to comment Share on other sites More sharing options...
