The S1 switch will give you an endless array of tones.
Recommended if you want to transform your American Deluxe into a Lonestar (Fat Texas Special) guitar. Do you think they would give it a better blues sound? The Texas Special/Pearly Gates combo gives you a nice blues sound with lots of Texas grit from the two single-coils and a huge dose of snarl from the humbucker.
Keep the S1 switch to split the Gates humbucker.
