I've been looking for a footswitching solution for hybrid guitars with piezo and magnetic pickups. Amazingly, nobody makes a product that's suitable to me, so i've been looking at Lehle and Loooper for options. (Ideally, i'd want a stereo pan/blend pedal that has both signals at 100% in the middle position, but nobody makes that.)
In the next few months, i'll likely be ordering a custom A/B box from Loooper that has Magnetic In/Out and Piezo In/Out, with switches to activate one, the other, or both. It'll also have a tuner/mute button with a dedicated tuner output.
