Glad you went back to zero with the pups for now. Pups are only part of the power generator. The other part is the strings. You should try experimenting with various string alloys and string gauges. These variables work subtly with the pups to develop tone and output. Something as far off as a different guitar pick material or thickness can also impact tone by impacting attack. I love most of the Squier lineup. Not a particular fan of the Affinity, but that's just me. If I had one wish, I wish they would come with Fender Vintage slotted tuners installed, but I find the stock tuners work fine. Perhaps you will notice an improvement in tone with the new saddles, perhaps not. But it is worth a try if you don't like the standard 3-piece. An incredible number of variables effect tone. Tone is a journey, not a destination.
