Start with a clean amplifier sound at a comfortable volume. Guitar controls are easier to hear when heavy distortion and effects are turned down. If you need help identifying a pickup or the bridge, use the guitar-parts guide.
Volume
The volume control changes the signal level leaving the guitar. Lowering it usually makes a clean sound quieter. With an overdriven amp or pedal, it can also reduce distortion. The exact response depends on the guitar circuit and the equipment that follows it.
Some guitars have one master volume; others have a separate volume for each pickup. On circuits with interacting controls, turning one pickup’s volume fully down can affect a combined setting. Check the model’s control guide.
Tone
A conventional passive tone control rolls off high frequencies as you turn it down. Listen for a less bright sound. The numbered setting is a reference for returning to a sound you like, not a measurement of treble in decibels.
The two tone knobs in the photograph need not control the same pickups on every Strat-style guitar. Some circuits assign them to neck and middle; others include the bridge pickup. Active electronics, push-pull knobs and modified wiring can behave differently.
A common five-way selector
For a conventional three-single-coil Strat-style circuit, the usual pickup choices are:
| Position | Pickups selected |
|---|---|
| 1, towards the bridge | Bridge |
| 2 | Bridge and middle |
| 3, centre | Middle |
| 4 | Middle and neck |
| 5, towards the neck | Neck |
Use the named endpoints rather than relying on “up” and “down”, which change with the guitar’s orientation. These five choices are shown in Fender’s Standard Stratocaster service manual. That model’s tone-control assignments also illustrate why the circuit matters.
A five-position switch does not guarantee these combinations. Guitars with humbuckers, special switching or replacement wiring may select split coils or other connections. Consult your exact model’s diagram before treating the table as its specification.
Try one change at a time
- Choose the bridge pickup and play a short phrase with the volume and tone controls fully up.
- Play the same phrase on the neck pickup. Compare brightness and attack without changing the amp.
- Return to one pickup and lower its tone control gradually. Listen for the change in high frequencies.
- Restore the tone, then lower the guitar volume. Notice both loudness and any change in distortion.
Keep the amp at a comfortable level throughout. If one tone knob seems to do nothing, check whether it affects the selected pickup before assuming a fault. Continue with how guitar pickups work to understand why changing position changes the sound.
