So the Dallas Arbiter Wah Face is a version one & I think was made by Shin El.
Many years ago I had a Shin El Fuzz Wah in this style casing.
Non functionality was down to a bad dpdt switch, both sides of the switch latched to bypass mode & wouldn’t switch regardless of button pressing. Cut out the switch & hard wired to effect mode & it all came to life.
Reflowed all the bad soldering & re-ended most link wires as they didn’t look good.
New switch ordered for tomorrow.
