I'm familiar with and proficient at circuit board repair / assembly
techniques. I have heard about a modification that can be done to the
mackie onyx boards to make the direct outs incorporate the EQ.
Searching the net reveals nothing useful other than companies willing
to charge me $300 for this option.

I suspect this mod is quite easy and relatively non-destructive. Can
anyone tell me how to do this myself?

Thanks in advance,
Mario
