I have always been bitterly disappointed with my Gretsch G5120. I replaced the tuners to Grover Sta-tites, got a bone nut and put in a roller bridge but I realised that the issue, once it stayed in tune, was the stock pickups. I bit the bullet and ordered rings and classics and after watching the online video installed them in about 40 minutes. I cannot believe how good the guitar now sounds. It has all the twang I always expected and the tone is just incredible. Don’t question whether-or-not you need these in your G5120. Just buy them. I cannot put this guitar down now - best upgrade I have ever done on any of my 6 electric guitars.
