Spark App - FAQ

Follow the Bluetooth Connection Troubleshooting Guide. If the issue persists, contact Support with:

• Phone / tablet model
• OS version
• Spark app version

Common causes:

1. The amp's Audio is connected to another device.
2. You denied the pairing request.
3. You previously paired with BLE by mistake.

Fix: Turn off other connected devices, go to your phone's Bluetooth settings and manually pair "Spark [Model] Audio", then reboot both the amp and the app.

Go to your phone's Bluetooth settings and connect to Spark [Model] Audio. If it's not shown, put the amp in pairing mode (Bluetooth indicator blinking), then find and connect Spark [Model] Audio in the device list.

Make sure Bluetooth is on and permissions are granted. On iOS: Settings → Apps → Spark → ensure Bluetooth access is enabled.

This is a YouTube security check triggered by your network — not a Spark app issue. Try these steps in order:

1. Turn off VPN / proxy.
2. Disable antivirus web protection.
3. Restart your modem and router.
4. Try a different Wi-Fi network.
5. Switch to mobile data.
6. Disable router-level security (e.g. xFi Advanced Security).

No. If you see a login prompt, it's a YouTube requirement — not the Spark app. Usually caused by VPN, proxy, or network restrictions. Try disabling VPN or switching networks.

Known UI issue: the preset tag may be missing. Verify by checking whether J.H. amps (e.g. J.H. D-Show Master, J.H. Sun 100S) appear in the AMP menu — if yes, your license is active.

The J.H. Legendary Wah disables Chorus / Flanger / Vibrato / Cloner Chorus on Spark 40, MINI, NEO, and NEO Core due to DSP limits. Spark 2, EDGE, and LIVE are not affected.

Delete and reinstall the Spark app.

See: Backup & Restore Presets.

Presets saved on an amp stay on that amp only. Presets stored in the Spark app itself carry over across different Spark amps.

Yes. The Spark app supports backup to Dropbox and uploading / downloading via ToneCloud.

See:

• Backup & Restore Presets
• Exploring the ToneCloud®

No. Dropbox backs up all presets in the Spark app as one set, regardless of which amp was connected. They can be restored to any Spark amp.

Artist-created presets are on ToneCloud. Open ToneCloud and tap the "Artist" tag.

No. There are factory presets built into the amp, plus many more free presets in the Spark app. You can also find thousands of free presets by logging into ToneCloud.

Yes. As long as you own a Spark-series amp, the Spark app is free to use on iOS and Android. You may optionally purchase expansion packs for additional amps, effects, and features.

No, and there are no plans to release one. All tone editing must be done via a mobile device (iOS or Android). On computers, Spark amps can only function as USB audio interfaces.

Workarounds: use a larger tablet, or mirror your phone screen to an external monitor.

No. The Spark app is only an editor — all DSP is handled by the amp hardware.

No. The signal chain order is fixed due to DSP design constraints.

No, the tuner frequency cannot be adjusted.

15 minutes.

Because users can watch YouTube videos in the app, and some music videos may contain content unsuitable for minors.

Auto Chord detects common guitar chords (major, minor, power, 7th, m7, etc.), but accuracy varies depending on the song's arrangement and audio quality. We are continuously improving this feature.

Auto Chord does not support transposing songs. However, you can transpose Smart Jam / Quick Jam tracks.

Not possible due to copyright restrictions. Use the built-in YouTube engine to search for songs.

Contact Support with:

• Device model
• OS version
• Spark app version
• Which drummer triggers the crash

Smart Jam does not work with headphones plugged in — it uses your phone / tablet's built-in microphone for audio recording, which is bypassed when headphones are connected.

Log out of the Spark app, close it completely, then log back in. Also check your internet connection and update the app to the latest version.

The Spark AI feature has been upgraded — it now generates one customized preset based on your text input, instead of the category-based presets from earlier versions. The old category icons and pre-shot sounds have been replaced by the text prompt interface.

No. To avoid issues for users who haven't purchased the pack, Hendrix content is excluded from Spark AI. You can manually add them to your signal chain after Spark AI generates a preset.

The Looper is available on Spark 2 and Spark EDGE only.

• Simple Looper — up to 60 seconds of recording.
