That's what I came in here to say.  I tried it again yesterday to be sure.  I'm running 4 cable method with 2 amps after an ABY and then the loop of my Quick Rod.  I realize I'm the noob in the room but I was standing in front of both with a MIM strat and gain up on both and didn't hear any difference on or off (in tone).  Metal riffs too.
Wow, you must really like the KHDK stuff 

  I've heard so many good things.  OD pedal specifically.  Not sure which one.
