Hey Everyone! I need some advice about my telecaster, it is a Squire affinity, pretty sure its an anniversery model, it came black and white and I have had it for about 11 years. I have had several things changed about it, 6 saddle through the body bridge, new tuners, and Neck pickup, DiMarizo blue velvet strat I am pretty sure and I think a twang king ended up in the bridge. I was only about 13 years old when I had this work done so i cant be 100% sure whats in it but what I am getting at is it is my number one. As crazy as this may sound I havent found another telecaster that sounds better to me, it has my sweat, dings, war marks, and neck wear as well. I dont mean to ramble to much but this is very important to me. over the past several months I have noticed some small problems starting to develop with it which concerns me alot because like I said its my favorite guitar and I want to do play it forever but I know a few things are going to have to be done to it to make that happen, Please know that I havent worked on guitars much so Im learning as I go, just always focused on playing, and also I do my best to take the best care of it other than the natural wear so any advice is very much appriceated! 1. It has a 6 saddle bridge, Im going to say more of a modern one because it has the 2 allen screws for eash string, I have noticed that they along with the intonation screws are starting to rust. should i replace or will it be ok? 2. The pickup magnents are starting to show signs of rust as well which really scares me because I am really afraid that I wont be able to find the same tone with other pickups so I really dont know what to do here. 3. The small E string dosent respond as well as the rest of the strings for some reason and the B string has a buzz to it, kinda sounds like a sitar, dont know how to fix that. 4. the guitar overall doesnt sustain well, I dont know why that is. 5. the neck is showing cosmetic wear, I really like the look because it gives it character, what I am wondering here is, is it just cosmetic or actually hurting the guitar? Thanks so much for all of your help!
