Product questions

Good to know.

Connect a compatible phone or tablet to the USB-C OTG port with the correct data cable, select the amplifier as the audio source if prompted, and start recording in your app.

CLEAN provides a clearer tone with lower gain. DRIVE adds saturation and distortion. Begin with low GAIN and volume before switching channels.

Use the REVERB and DELAY controls to add space and repeats. Adjust Delay TIME and FEEDBACK gradually to avoid an overly dense sound.

Yes. Connect wired headphones to the 3.5 mm headphone output and keep the volume low before putting the headphones on.

Use wireless audio or the AUX input. Adjust the source-device volume and amplifier playback level separately.

High gain naturally amplifies noise. Fully charge the amplifier, avoid playing while charging, reduce GAIN, and check the guitar cable and pickups.

1. Confirm that the cable supports data rather than charging only.

2. Verify device compatibility and permissions, reconnect the cable, and restart the recording app.
