A clean tone on a guitar amp means the sound stays clear with no distortion, and it comes from the gain and volume settings. Keep the gain low and let the volume carry the sound, with treble and bass near the middle. The Fender and CXLWZ amps below list gain, volume, treble and bass knobs.
Start with the gain low
Gain sets how much the amp drives the signal, and high gain is what pushes the sound into distortion. Turn the gain down to the low end of its range, then raise the volume to the level you want. The CXLWZ listing says its gain, bass, treble and volume knobs dial in tones from clean to distorted, so low gain is where the clean tone starts.
Set treble and bass near the middle
Treble and bass shape the tone after the gain is set. Start with both knobs near the middle, then move one at a time and listen for the change before you move the other. The Fender Champion II lists treble and bass among its controls, and the CXLWZ lists the same knobs, so both amps let you adjust each end of the tone on its own.
Use the clean amp voice first
The Fender Champion II has a single channel with a selectable amp voice, so pick the clean voice before you adjust the knobs. The Spark 2 and Spark GO list amp models in their apps, so choose a clean amp model there before you set gain and volume. Start from the clean voice or model, then adjust the knobs to suit the guitar.
Keep effects low or off at first
Effects sit on top of the clean tone, so set them after the gain, volume, treble and bass are where you want them. The Fender Champion II lists reverb, delay, chorus and tremolo, with an FX level knob to set how much effect you hear. Turn the FX level down first, then raise it a little at a time until the effect sits behind the clean tone.
Practice quietly with the headphone output
The Fender Champion II and the CXLWZ amp both list a headphone output, so you can set the clean tone without playing through the speaker. Plug headphones in, set the gain low and the volume to the level you want, then adjust treble and bass. The AUX input on both amps lets you play along with music from a phone while you set the tone.

Frequently asked questions
What gain setting gives a clean tone?
A low gain setting. Gain drives the amp into distortion as it rises, so turn the gain down and raise the volume instead. The CXLWZ listing says its knobs dial in tones from clean to distorted.
Where should treble and bass sit for clean tone?
Near the middle. Start with both knobs in the middle, then move one at a time until the tone suits the guitar. The Fender and CXLWZ amps both list treble and bass controls.
Do I need effects for a clean tone?
No. A clean tone comes from the gain and volume settings, and effects only sit on top of it. The Fender Champion II lists reverb, delay, chorus and tremolo, which you add after the clean tone is set.
Can I set a clean tone on a small practice amp?
Yes. The Spark GO is a 5-watt amp and the CXLWZ is a 20-watt amp, and the CXLWZ lists gain, bass, treble and volume knobs. Set the gain low, raise the volume, and keep treble and bass near the middle.
