Dumble Clone (180 degree) to 1/4-inch interface cable Bypasses my Amps EQ Section

Hi,

I have a RedPlate Blackline Amp and had a a custom Dumble Clone cable made to switch between my amps channels, and I just noticed that when I have this cable connected I lose all control over my Amps EQ section for both channels. Any help or insight on this would be much appreciated
 
The boost on many Dumble type amps works by disabling the tone stack. Turn off the boost and it should come back. Please note that the boost function may be inverted (boost is on when the function switch is off and vice versa). If that's the case, and you're using a Mastermind PBC or LT, you can turn on the Invert switch for that function switch to fix the inversion.
