Hey all, just finished my first vero build.  Made a DOD 250 and, surprisingly, it worked first try.  Lots of gain and pretty nice crunch (I used LEDs for the clipping diodes), though I have not had the chance to really crank it for real. 
So I put an indicator LED in and connected it as I have in the past, neg leg of the LED to the 3PDT, pos leg (thru 4.7K R) to the + on the board.  This time however the led stays on no matter if the effect is on or off.  In the middle of some actual work right now so I have not had time to troubleshoot, but thought I would drop a post here to see if there are any ideas. 
Of course most important is having a new working stompbox, just gotta get that light right.
thanks.

  IF your'e using an Spdt of the 3pdt, one middle lug and an outside lug [on the circuit path side, not jumper], the LED Has to turn off when the switch defeats by opening the LED/4k7 circuit between V+ and Gnd.
Convention creates following, following creates convention.

OK I figured it out.  Using shielded wire on the ins and outs for the first time and it makes things a bit tighter on the switch, I had inadvertently attached the ground wire to the LED wire, hence LED always on. Cleaned that up and the pedal works great, LED and all.

Oh, sorry not to give props.  i used your layout, dragonfly's, that is.  I don't think I subbed any parts either.
thanks for the valuable resource!!
