After recently looking over some wiring diagrams for 2x vs 3x setups, I realized the 2x selectors seem to include an option for Bridge + Neck (Series) which is NOT one of the options on the 3x selector. 3x selectors seem to only have Bridge + Neck (Parallel) while the 2x has Bridge + Neck in both Parallel and Series.
I currently have a custom 6-way selector on my D-ROC Custom 5, and the Bridge + Neck (Series) setting is probably my favorite of all, so it was interesting to see this setting exists on 2x models but NOT 3x (at least, without a custom selector).
Maybe that’s why the Bridge + Neck seemed to sound better on the 2x? Either way, I was a bit surprised to learn that setting only exists on 2x models.
