MarkBass LMK - mod/make effects loop work with both channels?

Hi,

I have a MarkBass LMK. I want to use the effects loop to effect both channels (it only works on one, the "master" channel).

Is this possible? Is anyone aware of any mods for something like this? The manual did not detail that the EFX loop would only work on one channel, and using my effects on both of these channels was one of the reasons that I purchased it!

Thanks!
