No power needed!! Just plug and go smile.gif so no "euro conversion" needed smile.gif you plug your guitar straight in.

This looks interesting though....

Maybe a good mobile device when the reason of hum is a power connections on the stage. Unfortunately...Didn't see european plug version

No power? What does it run on? laugh.gif

Your reply sounded like a commercial for a magical device that people in the universe of Harry Potter would use laugh.gif

Check the link Todd - I've posted some other device they make - the one You plug directly to the "wall" and then You have a filtering for Your full rig...Great when some @rshhole connects lights and p.,s to the same power line tongue.gif

God... I had an awful feedback noise last evening onstage - I have no clue why it happened, but it kinda ruined my whole mood - thing is, at the soundcheck - everything was in place sad.gif

I had to play 'Domination' by quickly turning the volume pot on and off between the parts where the guitar is not playing during the verse part laugh.gif

I am sounding like a commercial smile.gif These guys to make some spiff gear that loads of folks use in addition to the ISP decimator products to tame noise. These two together are the Magic Sauce of noise prevention smile.gif I"m sure Harry Potter has a rack mounted Decimator so he can run stereo cabs and have multiple inputs smile.gif

It came all of a sudden right before the first verse was starting - HELL! What am I gonna do with all that noise? laugh.gif The reaction was instantaneous and not forethought - but it was pretty hectic to keep up with it all the time.. yes mate, the stage is such a fun fair ain't it?

Most of this post is going to seem rather obvious and basic but I just want to state a few things in a simple way.

Probably because I don't use high gain, I don't seem to have serious hum problems even though I've got single coil pickups in my 1954 Gretsch. That said, most of the time when these problems do arise, it is at a club that is in an old building and there are serious problems with the club's electrical wiring due to additions and modifications having been done by people who are not qualified electricians. Many times different outlets and circuits will be out of phase with each other and ground connections may not be adequate. I have gotten some nasty shocks and burned lips from microphones when the PA system was out of phase with my guitar amplifier. Needless to say, in Europe with 240v current you can be killed by this. Add stage lighting circuits with dimmers and electrical noise gets totally out of hand. Most of the time when I have had trouble with hum, it has been due to lighting dimmers which produce all sorts of dirt in the AC service.

A comment was made about P90 pickups producing a lot of hum. I have a 1949 Gibson ES125 with an original P90. I have almost no hum problems with that guitar. Similarly, I don't have many problems with my Gretsch with original Dynasonic (DeArmond 2000) single coil pickups. I attribute this to two things. First, I always stand or sit with my body between the amp and my guitar (my back toward the amp) which shields the amp and guitar from each other. Secondly, I run the volume controls on my guitars wide open or nearly so (which gives a solid signal to noise ratio through the guitar patch cable) and control my volume with the volume control on the amp. This produces a clean sound with very little or no audible hum. If you like a lot of gain and distortion, this won't work for you, but if you like a clean sound it will solve most of your problems.

If at all possible, put some distance between yourself and the amp...one meter will usually do the job. I have seen players who complain about AC hum actually sitting on top of the amp while playing! This will absolutely guarantee a lot of hum. One last thing...make sure the ground wire in your guitar is solidly connected to the tailpiece or bridge so that the strings are solidly grounded, this way your body will be grounded when you are touching the strings completing the shielding of the guitar's wiring when you are between your guitar and amp.

Heh, I experienced the burned lips thing myself... and the ground wire being dispatched as well. But in the case of the gig last month, I found out there was nothing I could do in mid performance - I even ran away from the amp as far as I could go laugh.gif

Thanx for sharing Your thoughts Billy! I completely agree with You - even though I'm much Younger I already have expirience in this field and the things You mentioned are very clear to me. I was only hoping to get sort of "magic trick". You know....sometimes people invent something really refreshing for old, obvious issues and that's what I was trying to find. Seems like the best by far would be trying the dummy coil (getting prepared for first tests).

Sadly there isn't a "magic trick" that I"m aware of that will just put a "Harry Potter" fix on your issues. It would be great if there were though right smile.gif

Yep I know smile.gif But anyway even going through all those obvious things there is still something cool to find, like the hum-canceling devices You mentioned wink.gif So It's always a tiny step further i the gear setup quality wink.gif
