Seeing that, I ran a search.

https://www.premierguitar.com/features/artist-features/stevie-van-zandt-talks-guitar"Petillo takes care of the electronics on Van Zandt’s guitars. Almost all of the Strats are modified with an internal Alembic Stratoblaster preamp circuit, which Van Zandt can physically toggle on and off using a switch housed just above the input jack. Van Zandt tells me, “That came because I got annoyed with the whole pedal thing. I’m a performer onstage, and I’m integrated with the audience and I like the freedom to move. And if I’m across the stage and all of a sudden Bruce nods to me to take a solo, or there’s a bit in the song that requires a little bit of distortion, it’s just easier to have that; sometimes, I’ll need that extra little boost for a part I’m throwing in, and it’s convenient.”"
