LED wiring for Afterblaster for my first attempt at a combo build

[BlackCatChicago]

Hi builders!

Just completed my first combo build in an attempt to make my own version of the JHS Double Barrel.  I called mine the “Blues Screamer”.  Sounds amazing with any guitar I throw at it and stack really well with my other pedals, especially my Klon clone.  Everything is working as I planned it except one thing.  I couldn’t quite figure out how to wire the LED to the extra gain stage of the Afterblaster so that the LED light will be on when the extra gain stage is engaged.  The LED is one of those pre-wired LED with the bezel I got from Love My Switches, thought it would save me a little bit of time wiring the resistor to the LED itself and put it in the bezel.  The LED is always on now with the way I wired it.  Any idea how I can change it so it’ll only be on when the gain stage is engaged?  Hopefully the gut shoot is good enough to show what I did there.

Thanks in advance for your help!

If it’s a standard single colour, wire the LED anode plus to the middle pad and LED cathode negative to the outer pad without the white box

Jumper R5 if your LED already has the current limiting resistor

I actually already have another LED wired to the Afterblaster to turn on when the Blues Buster is engaged.  The 3PDT footswitch in the middle is wired to the where the dip switches would’ve been on the Afterblaster.  Is there a way to wire the middle LED to the middle 3PDT footswitch so that LED will turn on when the extra gain boost is engaged via that footswitch?

You have an unused set of three contacts on that middle switch.  You can wire the LED to the pair of lugs that are active when the boost is ON.  Provide power and a CLR if required to the LED anode.  Wire the Cathode to the outer lug and connect the middle lug to ground.

Thanks! I’ll give that a try!

Had a little time to try it out, and it’s working just as intended!  Thanks so much for the help!

Looks fantastic and I’d love to hear it!  Could you post a clip or two?
