Bass guitar amp settings are the gain, EQ and volume controls, and they shape how loud the bass sounds and how much low end, midrange and treble come through. Start with the EQ at the middle and the gain low, then adjust each control on its own. No setting works for every bass, amp and style.
Start with the gain and volume down
The gain control sets how much of the bass signal goes into the amp, and the volume control sets how loud the amp plays. Turn the gain and volume down before you plug the bass in, then raise the volume until you can hear each note clearly. If the sound distorts when you play hard, turn the gain down until it clears.
Set the EQ controls to the middle
On an amp with bass, mid and treble controls, start with each control at the middle, so the amp adds nothing and takes nothing away from the bass. Play for a while, then move a control a small amount and listen to what changes. Bass adds low end, mid shapes the middle of the sound, and treble adds the top end.
Shape the midrange to sit with other instruments
The mid control shapes the part of the sound that sits with other instruments. Start with it at the middle, then move it down a little if the bass fights with other instruments for space, or up a little if the bass is hard to hear. Small moves matter more than large ones, since a small change in the mids changes how the bass sits in the mix.
Use headphones for quiet practice
The headphone output lets you hear the amp without the speaker sounding. Turn the volume down before you plug the headphones in, then raise it until you can hear each note clearly. If the amp has an aux input, it lets you play along with music from a phone or another device.
Write down a setting that works
When a setting sounds right, write down where each knob points so you can return to it later. Change a control at a time from there and listen after each change, so you know which control caused the difference. A setting that works for a bass and a style may not suit a different bass or style, so treat your notes as a starting point.

Frequently asked questions
Where should I start with the EQ on a bass amp?
Start with the bass, mid and treble controls at the middle, so the amp adds nothing and takes nothing away. Move a control a small amount, listen to what changes, and leave the rest where it is.
What does the gain control do on a bass amp?
The gain control sets how much of the bass signal goes into the amp. Turn it down if the sound distorts when you play hard, and raise it only until the notes come through clearly.
Can I use headphones with a bass amp?
Yes, if the amp has a headphone output. Turn the volume down before you plug the headphones in, then raise it until you can hear each note clearly.
How do I keep a setting I like?
Write down where each knob points when a setting sounds right. That record lets you return to the same setting later instead of starting over.
