How to fix an echoplex footswitch?

[marcus kirby <marcusloops@gmail.com>]

The record function on my edp footswitch is no longer working. From
what I understand, it's just resistors that need to be replaced,
possibly the footswitch itself?

If I open it up, I should probably just replace all of the resistors, yeah?

Any help, i.e. values of resistors would be appreciated.
