Adding a "direct out" to the Dirtbag

[reaganomics!]

I sort of want to put a direct out onto my dirtbag build like the memory man.  If it's like the Deluxe Electric Mistress I have then there's just a wire coming from the tip of the input jack to the tip of the "direct out" jack so the signal is getting split up. 

I'm sure that causes impedance/tone suck problems so I figured I could just stick a small buffer in there, and power it with the extra unused tip on the DC jack that gets used for the battery snap on regular 9v pedals, and have the ground going to maybe the extra pads on PCB. 

Would this work out fine?  I'm using the taller 125-BB, would the jacks have room pretty much anywhere, instead of cramped on one side of the pedal like on some other builds?

Looking at the original DMM schematic, tap a 150R resistor off of lug 1 of the blend pot to a jack, done.
