hummer

[jnumme]

I just recently purchased a new sting ray 4 with the 3 eq and today I noticed that when i'm plugged in direct (no pedals) to the amp with my volumes up and not playing I'm hearing a humming noise though my amp but when I touch any of the knobs or even the saddles the noise stops . can any one tell me what the heck is going on ???

Could just be somthing as simple as a dodgy lead.
My advice would be to try another lead an check you battery.

I used to get that all the time with my F3nder Jazz. Now with my MM Sterling...never.

Grounding issue...

Fluorescent lights. Dimmer switches. Dirty power. Loose wire. Aliens. Aliens ate my Buick. Hole in sock. Marshall guitar amp in vicinity. Not wearing tin foil hat.

You tell me.

Yeah, try using a diffrent "instrument" cable/lead. had gremlins in mine a while ago , lead works but created ground noise wen plugged in. changed leads an problem solved. i was using a sloder-free cable an (well im not a fan of them any more).

It's usually caused by "60-cycle" hum - Basically bad earthing in your house. Particularly found in older houses. My house was built to commemorate Queen Victoria's jubilee, so our earthing is pretty shocking. Lots of bad earth hum on active basses at my house!

As someone else mentioned, one big cause of this is dimmer switches on room lights. Can create havoc when you're playing at higher frequencies (with a lot of treble boost.)

hopefully just the cable not I can do about my old house
