Final Wiring of the 7-String LED Guitar

Now I’m not going to get into the complete step-by-step of how to wire this guitar’s pickups, as that can be found just about anywhere on the Internet.  As a reference, I used this schematic, as found on the Seymour Duncan website.  Note – I could have saved myself a LOT of time, if I understood one small difference between Dimarzio and Seymour Duncan pickups – Seymour Duncan uses a red wire for the “hot output” from the pickup, and Dimarzio uses black.  What I didn’t realize was that while this is a truly excellent schematic, I need to swap red for black to make this work for Dimarzio.  That could have been two hours saved…

Here are the two pickup wires, in their untouched state.  These need to be trimmed and stripped. 

I ordered two 500K control pots for this project, due to the high-output of the humbuckers.  250K might have worked, but I erred on the side of caution.   What I didn’t realize here, was that the volume and tone pots are the same thing.  It’s all in how you wire them that determines their function.

This is a stripped pickup wire.  The bare wire is the ground, and the colored wires are various things that I won’t pretend to understand.  I just used the “paint by numbers” strategy when wiring the guitars controls. 

This is a bit of a cheat shot, so just pretend you aren’t seeing the neck installed.  I wanted to show this picture as this is pretty much what my work bench looked like during the wiring phase of this project.  my iPad with the wiring schematic was never far away. 

Here’s another time when my solder buddy came in handy.  This is a shot of the neck pickup wiring, after beginning to follow the schematic.

The solder buddy was great for holding the tone and volume pots as well.  In this picture, you can see the glob of solder on top of the pot.  This is a “ground point”.  Maintaining proper ground is necessary to reduce the amount of hum and interference your guitar produces.

Lastly, here’s a shot of both the volume and tone pots installed, and the input jack in the final wiring process. Once this is completed, it’s time for final assembly!
