Hi guys and long time that I’ve been here. Hope everyone is doing well. Eddie texted me about an amp I had on the Facebook Market Place and we ended up trading. He traded me an HB SC-550 deluxe and an NC4 that is in great shape. So it was time to start to up grade it. Purchased middle and neck Neodymium Single pickups - True Vintage from GFS in 7k and a 9k. The bridge is going to be a SD Hotrail. Also going in is a vintage style narrow big steel block bridge. Now for the tuners, not sure what other squires have, but the stock tuners on these NC serial number guitars are stamped steel and stock they are pretty bad. 14 to 1 gear ratio and very loose tuners. So I took one apart and found that the post is the issue. The gap between the post and the mounting plate is pretty wide for a tuner. Went to the hardware store a purchased push washers 7/32nds and are super thin, in the area of a few thousands, but that are a perfect fit and take up all the slack in these tuners and made them smoother with no play. I don’t like to upgrade tuners unless they are a drop in replacement. I just don’t like drilling holes in a guitar neck. You will end up with a more stable tuner by doing this. Please check out the video of how i did it. Huge difference in the tuner and I mean huge. Hope this helps.
