A lot of modelers have at least one balanced input. If you've got passive humbuckers, you can wire-up the two coils as balanced-out. Has anybody tried this? I'm assuming it would sound basically parallel-ish.
What's rattling around in the brain bucket is to wire-up the two humbuckers to a 4-Pole On-On and then to a stereo XLR jack into the two balanced inputs on the modeler and then the modeler can handle the neck/bridge/blend switching. The On-On switch will then be able to toggle between Neck/Bridge and Inner/Outer.
