Why would you like to strip the better guitar of its parts to outfit a lesser one with them
Anyways, the Pacer Vintage has an FRT1000 MIK while the Classic has a cheap knock-off like XXX said. That being said, I bought an OEM FRT1000 to upgrade my Classic a couple years ago and it was a perfect fit. I just let the studs where they were and swapped the Floyd.
But again, it seems like you have a mid-level guitar and try to strip it for an entry level one. That makes little sense from my perspective. If you don´t like the more chunkier neck of the Vintage, just swap the neck of the Vintage for the Classic neck since the neck of the Classic is the very best part of the whole guitar in my opinion.
Practice cures most tone issues.
