SBMM JP100D Question

Hi everyone! I recently got a Sterling JP100D guitar as a gift from my wife. Does anyone know what type of material the saddles and sustain block are made of? I’ve been having somewhat of a strange issue in that for some reason the pick attack on this guitar is on the dull or muddy side. It seems to be a low-mid frequency in there that’s making attack on fast picked runs on the neck pickup sound more like a dull thud than the typical “click” type sound. I can play any of my other guitars and it becomes immediately apparent. I’ve tried several types of pickups in the guitar(PAF Pro, Liquifire, Air Norton, EMG 81 & 85, SD Alpha), different strings and gauges, different picks, more and less springs, blocking the trem with wood and metal. Nothing seems to help much and it’s seriously bumming me out because it’s a gift from my wife and I don’t want to sell or trade it off. I’ve considered changing the saddles to Callaham bent steel and trying the stone tone block. Any suggestions would be greatly appreciated. 🙂
