To make three-switch aux switch boxes for my Stompboxes using three momentary pushbutton switches are they single SPST or SPDT and how do you configure the contacts of the three switches into the Tip and Ring lugs of the TRS jack for correct switching of the default Eventide setup for preset, bank down and tap, etc? I have all the parts and know how to solder, just need a hookup diagram or description. Thanks! Really enjoy the forum so far, lots of great info!
