No S-series style clone guitars. But someone once did take an IB-7 and sand down the edges to make it very much like an S-series. It was a Guitar of The Month, back in 2017. https://www.buildyourownguitar.com.a...l=1#post130406. So you could do something similar.
The XB-1 looks to be a closer starting point for your requirements (general Ibz shape, 2x humbucker and fixed bridge), but the minimal controls (just volume & 3-way toggle switch) locations may put you off. https://www.pitbullguitars.com/shop/...itar-kit-copy/. But if you can rout, then some filling and routing could get you to where you wanted to be. All depends if you just want to put a kit together, or spend rather more time making it into your own creation.
