What brings you
to the bench?
You do not need to know the part name to find a useful starting point.
01I want to learnStart with the circuit, then meet its components.
Understand the fundamentals in a deliberate order. No account or required course.
02I want to fix somethingFollow the path before changing a part.
Use the troubleshooting guide to organise checks, then inspect supported connections in Circuit Lab. The diagram cannot diagnose your physical instrument.
03I want to change my responseExplore loading, values and the volume circuit.
Read how pots and capacitors interact, then compare a supported single-pickup electrical model. Split and coupled pickup response are unavailable; these tools do not predict acoustic sound.
04I want to wire a guitarConfigure. Trace. Take the drawing to your bench.
Use Circuit Forge to understand a supported circuit, then Wiring Generator for solder destinations and a printable connection list. Verify the terminal functions on your actual hardware.
05I want to build a kitTurn a supported specification into a practical build.
The Les Paul Kit Builder lets you review supported kit options, shaft fitment and component choices. Confirm availability and pricing in the builder; optional split circuits do not imply a matching kit.
02 / FOLLOW THE SIGNAL
A path you can
understand.
A typical passive-guitar journey. The tone circuit is a branch, and actual layouts and control order vary. This is an educational map, not an electrical simulation.
Pickup
The starting point
A passive pickup supplies the signal. Its electrical properties interact with the controls and the load; a wire colour alone does not establish a coil function.
Selector
Choose a pickup path
The selector closes particular contact pairs. Intermediate positions on a conventional five-way can connect adjacent throws. Inspect the actual contact model and verify your hardware.
Volume
Control the output
The volume pot provides a resistive track and a wiper. Its value and position affect loading and the electrical output. A supported single-pickup comparison makes the interaction easier to explore.
Tone branch
Shape the response
A typical tone control and capacitor form a branch toward ground. The main signal does not need to pass through the tone capacitor on its way to the output. The connection depends on wiring style.
Output
Signal and return
The jack tip carries the output signal and the sleeve provides the return. Shielding has its own physical role even where bonded to the same ground network.
