Good afternoon all, I am currently trying to build a foot switch for my Fender Power Chorus. I got some great help from Steve 78 and Norris Vulcan but I have now come to a dead end. Diagram in post. The pedal has a Channel Select, Boost, Chorus, and Reverb. The Boost, the Chorus and the Reverb are all working but unfortunately the Channel Select is just on. That I turn the switch on or off, it stays on. Interestingly enough the light of the Channel Select will go on and off when using the switch...the amp, not so much (argh). I have not posted a picture, as it is wired with alligator clips to test. This is my first time attempting something like this and I am certain I must have wire something wrong or out of sequence. Also, I have had to use a substitute for the 1N4448 diodes. Could those be the issue? Therefore, if anyone has a crystal ball or knowledge to help, I would be very grateful. Many thanks!
