Guitar amp settings are the controls on an amp: gain, volume, treble, bass, and effects such as reverb, delay and chorus. Gain sets how hard the signal is pushed, volume sets how loud the amp plays, and treble and bass shape the tone. Start with the controls near the middle, adjust one at a time, and add effects last.
Start with the controls near the middle
Turn the gain, volume, treble and bass to the middle of their travel before you play a note. That gives a neutral starting point, so each change you make after that is easy to hear. If a control is already at one end, move it back to the middle first, then play and listen before you change anything else.
Set the gain before the volume
Gain controls how hard the guitar signal is pushed into the amp. With the gain low, the sound stays clean and follows how hard you pick. Raise the gain and the sound breaks up into distortion, so set the gain to the amount of breakup you want first, then use the volume to set how loud the amp plays. Keep the volume low while you adjust the gain, then raise it to the level you need.
Shape the tone with treble and bass
Treble and bass are the tone controls. Treble adjusts the high end of the sound, and bass adjusts the low end. Move one control at a time and play after each move, so you can hear what that control does on its own. If the sound lacks low end, add bass before you add volume. If the low end is too strong, lower the bass before you raise the treble.
Add reverb, delay and chorus last
Set the base tone with gain, treble and bass first, then add one effect at a time. Reverb adds space around the notes, delay repeats what you play, and chorus doubles the sound. Turn the effect level up slowly until you can hear it, then stop. If the effect hides the notes, turn its level down before you change the gain or the tone controls.
Use the headphone output for quiet playing
If the amp has a headphone output, plug headphones into it and the speaker stays silent while you play. Set the gain, volume, treble and bass the same way, and start with the volume low. If the amp has an aux input, plug a phone into it to play along with music from the phone.

Frequently asked questions
What should I set first on a guitar amp?
Set the gain first, then the volume. Gain sets how hard the signal is pushed, and volume sets how loud the amp plays. Once those two are set, shape the tone with treble and bass.
Why does my amp sound distorted at low volume?
Distortion comes from the gain, not the volume. If the gain is high, the sound breaks up even when the volume is low. Turn the gain down for a clean sound, then raise the volume to the level you need.
Do I need to use the effects on my amp?
No. The amp plays without any effects turned on. Reverb, delay and chorus add to the base tone, so set the gain, treble and bass first, then add one effect at a time until it sounds right.
Can I practice with headphones on a guitar amp?
If the amp has a headphone output, plug headphones in and the speaker stays silent. Set the controls the same way you would for the speaker, and start with the volume low.
