Hi again !
Galvanic corrosion, as it is called when two disimilar metals are close together with a conducting medium between them, only may apply, as just stated, with two different metals. No problem if the guitar is made all with the same metal for all parts. Not quite sure how it works when the metals are nickel-plated though !

I don't think galvanic corrosion was a major pre-occupaton for National - they'd solder anything to anything - and I've yet to see an instrument fitted with a sacrificial anode...

The nickel plate would reduce the galvanic gradient and hence the tendency to corrode. Robin once told me that brass wells were nickel plated. However I take your point regarding National's construction methods and materials Stuart.
