okay well i bought myself a Jackson RR3 =]!!
but now it has hum...
the hum is always there (even when i put my hands of the strings) and when i play the mute quickly it goes louder for a short while..
the hum also only occurs when there is distortion...
it is not the cable because when i pull the cable out of my guitar and put my finger on the tip it does not make that hum sound!!
so yeah! does anyone know how to fix this??
would greatly appreciate it!!
i dnt wanna throw away my R12 000 guitar!!

If you bought it new, take it back to shop so they can fix it.
Try touching the scratchplate, if the hum goes away, then it is a earthing problem.
In other words, make shure there is a wire connected to your bridge(solder to the screw at the back of the guitar where the springs for the floyd rose is.) from one of the pots.
I also had this problem with an RR3 before where the earthwire weren't connected.

strangely enough i had a similar problem.
Got a peavey into a GT 8 into an ibanez artist. Plugged it in, in when i hit distortion, there was this massive him. Serious stuff.
After a while of trying to figure out what it was, i swapped the cable that is going from gt 8 to guitar with the cable that goes from gt8 to amp and the hum was gone.
it still doesnt really make sense to me... any ideas?

That sounds like a bad cable Lethe. High impedance on the guitar side shows problem cales pretty quickly, The GT-8 puts out a low impedance signal, which is a lot more tolerant of iffy cables.
Like Manfred I tend to think that Mayhem's problem is a faulty earth connection (probably to the bridge). If it goes away when you touch a jack plug casing (or other metal parts), then it definitely is. Sometimes excessive hum happens if you accidentally swap around the wires on the socket, but that would then get worse when you touch the strings.

nope taht didnt help...
the thing is i bought it before and had to send it back because of taht humm(the guitar technician could not fix it)
and i got a new one and its the same problem!!!

Are you playing your guitar near a CRT (Cathode Ray Tube) A PC monitor/screen or any florescent lights?
Try moving around the room to see if it gets worst/ better...
If its not magnetic /microphonic interference
Im also going with a grounding/earthing a problem...

This could be any number of things. The only way to track it down is to be methodical and isolate each part of your system one at a time and make sure that it's not something else.
Firstly, no electric is 100% quiet with tons of distortion and some are worse than others for a variety of reasons. Distortion makes everything louder, so it's not surprising you only hear it with distortion. However, try it with amp distortion and try it with pedal distortion - does that make a difference, or do both hum?
Have you tried other guitars? While you're getting the problem with one guitar, it may be that that guitar picks up a problem elsewhere in the system and it isn't the guitar itself.
Try plugging your amp into a couple of different wall sockets in the house - if the hum varies depending on socket, then it's faulty earth wiring.
Do you have more than one effect pedal powered with the same power supply? This can cause ground loops.
Check cables and try different ones.
That's all I can think of for now..
