Thanks to those who posted me schematics I got three of my four triple aux switch boxes completed (and painted Eventide blue) and the improvement in functionality is immense, particularly for the H9. So far I have them set up: TF- Repeat On/Off, Tap, Bank Down; H9- Hotswitch, Tuner, Preset Down; SP-Hotswitch, Tap, Preset Down; MF-Expression pedal. I plan to add one more for the second H9. Very pleased with my ET rig!
