Tips to minimize hum coming from the electrical installation?

[IMENATOR]

I am hearing a funny sound (I think you may call it fizz in english but I am not sure) at the end of notes. I hear some hum when I do not touch the strings of my guitar that goes away when touching/playing.

I will redo some wiring in my guitar since I am not 100% trusting some joints and parts so I will try go get rid of that part of the problem.

Are there any tips you may provide so I can change/improve the way I plug the amp to the electrical power that can be useful when at home or rehersal or even a gig? Any electrical device between amp and electrichal socket? Any good practice, kind of cable, etc?


Thanks in advance, and happy holidays!

That fizz is more likely to be something mechanical, such as a loose saddle.

mmm, that is interesting, I have a floating FloydRose brdige. I usually play low but today I crancked the amp and noticed. Can a floydrose be that "sentitive"? I will double check that everything is properly locked and will also put something to "lock" my bridge and compare. I don't have another guitar to test and compare

The best way to get rid of mains issues is to use a Power Conditioner of quality. Depending on the nature of your issues, solution can be simple or as complex and expensive as you can imagine.

First simple step, try to use some power conditioner of lower price and see if it filters the noise enough. An example is the Phonic PPC9000. I have this one between my mains plug and my amps and pedal power units, to decouple home's ground from my rig's ground.
Second step, try to use a pedal power brick with a transformer and isolated outputs. Voodoo Labs Power Pedal 2 Plus is a good example. This solution is way expensiver than the Phonic unit but, it worth it.
Third possibility is to put an small UPS unit between your mains plug and your rig. You don't need the unit to stand long time under batteries but, you need the unit to be providing a properly filtered and constant current/voltage. This makes it a bit expensiver, since you need a good unit here.

But, the standard in audio applications is Furman. Their lower end devices are already expensive as hell.
We want units with nice EMI / RF filters and, that's usually expensive.
Big issues can demand specialized filters to get rid of certain particular frequencies (the ones ruining the sound).

I am quite sure I am missing something but, more specialized people will chime in, expand the information and correct any mistake.

What kind of pickups are in the guitar? What you may be. Hearing is 60 cycle hum which is normal in a single coil guitar like a Strat or Tele

Im not a expert but maybe you need to shield your cavity where all the wiring is that might help

A recording of what you hear would be needed at this point.

Last night I rewired the thing, I also added a new ground wire for the bridge. It definitly improved the hum cancelation so when I untouch the bridge or strings there is a only a tinny difference in hum cancelation. I still need to get that recording and post it here.
