i must say that strap locks are a definite necessity when it comes to investing in your axe, weather it be worth $50 or $5000.
i replace all strap buttons with them immediately, i don’t a quire a new guitar without also getting locks for them!
i use Dunlop or Schaller, they are slightly different in the way they “clip on” but installation is rather the same. i used Dunlop mostly in the past, but have recently been favoring the Schaller ones.
on most guitars the glue and toothpick scenario is rarely needed. but when it is your only filling in the hole a bit, so removing the material later really isn’t an issue, so i don’t feel that im modding the instrument at all, plus the added protection is very much worth the use of the locks.
