Has anyone solved this wiring issue so the footswitch LEDS lite when the relay and feature in engaged? Or has anybody got a picture of the working Pedal connections?
Thanks,
Mike

Re: Ampdoc style relay boards available
The standard ODS foot switch wiring works that way, but you need a dedicated 12V lead to the foot switch. The circuit is shown in the schematics, including the one in the DIY eyelet boards post. The eyelet board .pdf has the circuit, and an alternate arrangement that lights the foot switch LED if mode is selected on the amp's back panel.
If you don't have the 12V feed, I believe you could put the indicator LED's in series with the foot switches (and therefore in series with the relay coils) and let the coil DCR serve as the current limiter for the LED's. The relay should still operate with the ~2V drop in the LED. A Marshall replacement foot switch with TRS 3-wire cable can easily be modified to work this way.
