For jazz guitar, set the amp to a clean voice or amp model, keep the gain low, and set the bass and treble near the middle. Add a small amount of reverb and set the volume to the level you play at. The result is a clean sound that keeps each note distinct.
Start with a clean amp voice
Select the clean voice or clean amp model on the amp before you touch any other control. Turn the gain down and set the volume to the level you play at. A clean starting point makes every later change easier to hear, and it keeps the sound from distorting before you set the tone controls.
Keep the gain low
Gain sets how hard the guitar signal drives the amp, so keep it low for a clean sound. Turn it up only a small amount at a time and stop when the sound starts to break up, then turn it back down a small amount. With the gain low, the amp stays clean when you play harder.
Set bass and treble near the middle
Set the bass and treble controls near the middle as a starting point. Play a few notes and change one control at a time, moving it a small amount and listening before you move the other. Leave the bass where the low strings stay clear, and leave the treble where the high strings stay clear.
Add a small amount of reverb
If the amp has a reverb control, turn it up a small amount so the notes have a little air around them, then stop. Too much reverb covers the attack of each note and makes fast passages hard to follow.
Use the headphone output for quiet practice
If the amp has a headphone output, plug in headphones and use the same control positions as for the speaker. Set the gain low, the bass and treble near the middle, and the reverb to a small amount. Check the headphone volume before you start playing.

Frequently asked questions
What gain setting keeps a jazz guitar sound clean?
Keep the gain low so the guitar signal stays clean through the amp. Raise it a small amount at a time and stop when the sound starts to break up, then turn it back down a small amount.
Where do I start with the bass and treble controls?
Start with both controls near the middle, then change one at a time by a small amount. Leave the bass where the low strings stay clear and the treble where the high strings stay clear.
Do I need reverb for a jazz guitar sound?
No. Reverb is optional. When the amp has a reverb control, a small amount adds a little air around the notes, and too much covers the attack of each note.
Can I use the same settings through headphones?
Yes. When the amp has a headphone output, use the same gain, bass, treble and reverb positions as for the speaker. Check the headphone volume before you start playing.
