Hi guys. I have this bass guitar, a Squier, and the tuners were upgraded to Schaller tuners. I was playing it for a while before I noticed that the bushings (I think thats what they're called) have not been fitted flush with the headstock. I don't have a known guitar tech that I go to, and I'd like to do it myself. I don't have many tools, but is there a way that I could fix these properly? I know I'll have to remove the tuners and then knock them into place, but is there a better way to do it than to user some heavy tool to knock them in? I'm attaching pictures so you get an idea. The 4th string tuner is the worst one, that's sticking out a lot Thanks!
