I bought this loaded pickguard from Sigler Music in 2016. The Holy Grail are great sounding pickups. These haven’t been used more than a couple hours. There is a spec sheet in the pictures that I received with the whole pre-wired pickguard. The product is a pre-wired Fender Stratocaster loaded pickguard with Lace Holy Grail pickups. It is designed to fit electric guitars, with a white vinyl material and a parchment color name. The unit features Lace Holy Grail pickups from the brand Lace, and is specifically for Stratocaster models. Made in the United States, this pickguard offers a rich and authentic tone for guitar enthusiasts looking to enhance their instrument’s sound.
