Brite Sounding Majesty

I recently purchased a Purple Majesty from where I work and customer service was very kind and sent the updated Preamp and Electronics but kept the original Pickups. I have noticed when playing this guitar live , It sounds very Bright, Thin and Brittle compared to my Les Pauls and EVH. I’m concerned the Majesty is just not a good match for my set up. The Piezo is almost Un usable
I play a Marshall JVM 210H through a Marshall 4×12 cab loaded with Vintage 30’s. My Pedals are a Boss Delay, Ibanez TS9, Bad Horsey wah, All my other guitars sound amazing to me, But this one is just not warm at all. Its a beautiful guitar
