Hi, I have CV Tele and Duo Sonic. As I am trying to change the pickups, I am wondering if I would have to also change bridge, nut, or electronics on both guitars... 1. Was the vintage Duo Sonic in "series" in the middle position? 2. Do I need Danelectro "on-off-on" switch to change it to series? Can I do it with stock one? 3. Are electronics (pots, wires, and etc.) that bad in Classic Vibe Tele and Duo Sonic? Do I need replace them? 4. I want to have that vintage sound back in the 50s... But in my opinion, as long as they work fine and do their job, electronics, bridge, and nut are fine to stay... Is there much difference in CTS pot and better bridge? 5. If so, any recommendations where to get the best parts for best price..? Thanks!
