Getting a bit flakey on a Behringer SL2442 mixing desk.
Just 3 control lines out , ground and 2 lines taken high via 4K7 to 5V. What
would be inside , 2 sets of 10 resistors? All wrapped up again , different
problem repaired and only noticed at final checks so cannot investigate.
Owner only uses one effect so fingers-crossed will not need replacement or
its fellow
