Hi, I've been have problems with hum my guitar/cables are picking up.

Described [="http://recording.org/studio-construction-forum/45187-electrostatic-my-room.html"]here[/]="http://recording.or…"]here[/] in my very popular electrostatic thread =)

So I came across this thing called the [[url=http://="http://isptechnolog…"]Decimator ProRack G from ISP[/]="http://isptechnolog…"]Decimator ProRack G from ISP[/].
In audio and video clips it seems to cancel out hum and static noise very well.

Channel one eliminates the 50 or 60 cycle hum, buzz, stage light noise and any other noise picked up directly by the instrument. The second channel is inserted into the effects loop of your amplifier (requires a series effects loop) and this channel will clean up the high gain preamp noise, ground loop hum, and any other noise that you have in this chain.

Has anyone had any experience with this thing ?

Try this. After you have recorded your guitar track, go back to the top. Lie your guitar down with all of its buzzing hum and record that without touching the guitar. Now take your recorded guitar track that you played on and combine it with the empty buzz hum track. You will invert the phase of the buzz track. When you combine the two, most of the buzz & hum will in all likelihood cancel out leaving only the notes you play audible. Of course your guitar track will be 2 generations down but aren't we talking digital here? It was a bigger concern than analog but that never stopped me. It's a matter of taking one sound and combining it with another identical sound out of phase. It magically and electrically cancels out each other. Easy to do. Just takes a secondary pass to accomplish it. And then with a clean track you can erase the other two.

1-1 = 0 or is that mathematically too complicated?
