Do high shielded cables like Mogami reduce airborne emi noise that's picked up by the pickup?
No.
Shielding your guitar will help and then finding and reducing or eliminating the source.
No.What about Ferrite Core Rings on 1/4" Cables and USB Cables like these?

And the cavity covers. And make sure there's electrical contact between the covers and the shielding of the cavity itself.Shield the entire guitar control cavity and the pickup routes. Still noisy?

Got tiny cuts all over my hands from handling the foil though.
Yeah, there’s no need to cut your fingers. Just find or fabricate a burnishing tool. You’ll get more even results, too.You have to use thimbles on your fingers and guitar picks to get in all the little crevices, so you don't cut up your fingers.
Instead of copper foil tape, I've been using HVAC Foil Tape and just fold the seems to keep continuity because the glue isn't very conductive. It's a lot lower price and you can get it at most hardware stores.
Been there, done that. Not much is better than a guitar free of unwanted noise, though, so it's worth the BS&T to get there....Got tiny cuts all over my hands from handling the foil though.
My main workhorse guitar that I gigged with for probably over 10 years was a Warmoth parts-caster. I lined the control cavity and pickup cavities with copper shielding foil and attached it to ground in multiple spots. Quietest guitar I've ever played. Got tiny cuts all over my hands from handling the foil though.
So if I use an ISP decimator to quieten it down, does it go before or after the modeling unit?
