I recently purchased a new squire classic vibe jag and while inspecting the shielding I noticed that there is no shielding or grounding wire in the tremolo cavity (the other cavities appear to have shielding paint) - from all the info I’ve seen on forums & YouTube , the shielding and grounding is said to be needed for the trem area as well. The trem cavity does not even have a connecting drilled pathway to the other cavities. Is shielding not needed with newer/classic vibe jags? - thanks!
