I too am converting an AGO pedal board using reed switches and MIDI encoder. It's becoming a fun project. I stumbled across a YouTube video with details and a demonstration of a similar project to mine. I'm using the same reed switch assembly shown in the video (from
www.midibotique.com) but with a different MIDI encoder. I'm also attaching the switches on the pedalboard itself vs an add on box shown in the video.
https://www.youtube.com/watch?v=AoFcEz0MsmIWhen midi-fying an AGO pedalboard, with its radiating design, care needs to be taken so the magnets and switches are all proportional so all the pedals trigger the contact signal in a uniform manner. Specs I read say a pedal dip of about 1/2" with a note sounding at the 1/4" travel.
