I had my LMII open the other day to move the jumper on the PCB that controls whether the DI out is pre or post EQ. I noticed that there's a small plate covering a hole on the back of the chassis that's held on by two screws. That hole seems like it would be a prefect location to place an SPST switch that would do the job of the jumper. Has anyone done this? It seems like it would work without problems, but I could be wrong.
