If I have a stainless diamond plate pickguard made for a couple of my guitars (an HSS strat and an Epi SG) will it produce more hum or have any other negative effects, I am a reasonably proficient guitar tech so don't be afraid to talk the talk, other than the increase in weight which is fine, will there be any negative/positive effects on my tone? any insight is appreciated...
My Guitars:
80s Charvel RR V
80s Kramer Baretta II american
1990 Jackson Dinky
80s B.C. Rich STIII
Fender MIM strat
Hamer Special
LTD F-250
80s Westone
Epi SG
My Custom "super squier"
Custom Kramer 300st
71 Yamaha acoustic
I doubt it - Just make sure you have the entire pickguard and your entire cavities sheilded.

Gibson released the new century series which are basically white wiht a massive metal plate on the enitre front of the guitars.

Probably not, be sure your diamond plate isnt' magnetic, so it wont' cause any problems with teh pickups. Other then that you shodu lbe fine.
i dont think you even need to shield the metal pg, and the cavities should allready have the conductive paint
