Please remember the copper taped plate is because guys expect everything to be slathered in copper. It’s just easier than explaining it.
There is a good reason for doing this, and another reason not to do so. Sadly, they kind of cancel each other out.
Electrolysis is the propensity for two dissimilar metals in strong contact with each other to try to exchange molecules (actually, electrons from molecules), which then leads to what we usually call corrosion. It may take time, but eventually it will come out of hiding, and I'm sure you can guess what comes next....
For the best conduction of current in the job of noise suppression, copper to copper should be employed. Lifting and inspecting the copper from the back(under)side of a chromed plate my be more difficult, but over such a large area, I'd guess that the need won't be more than every 10 to 15 years. And your adhesive material will likely slow that process appreciably.
Rule #1: All Lives Are Final. Make sure that the life you have just been issued is appropriate for your needs, before departing the womb.
Rule #2: In case you don't like the life you have, see Rule #1.
Hi Davidskiwan, I’ve been reading your initial thread and wanted you to know that I built a Passive Treble Bass Concentric Telecaster but never finalized the diagram. But with help from Retread and Sumgai, I’ve finally updated it. I‘m hopeful it will help you with your planning for your setup (plus I had forgot to put the finalized up on the forum). Although mine is tied to a 3-Way Switch, it could be easily altered to work with a 5-Way Superswitch that would give you N,B+N Parallel, B+N Series,B+N Series Out of Phase and B. Although not the full array you’ve been discussing with Ash using a 6 way, it could be another way to go with your setup. You’d obtain the majority of tones you want to achieve.
