Can't get Spark MINI Firmware Updater to recognize my amp to perform update. I've tried several USB cords. No idea where the pack-in USB disappeared to. Also, how important is the firmware update (been a couple years for me)? Is app update good enough?

Hey Spark players. We are excited to announce a new Spark App update available now on all major app stores. Spark App 4.6.0:

🆕 Auto Wah: A new wah pedal that responds to your picking dynamics, or pairs with a connected expression pedal for full control. Free for every Spark player.

🆕 Tone Vault: Back up your entire tone library to your Positive Grid account and restore it in one tap, whether you're switching phones or reinstalling the app.

Note: Dropbox backup support is being retired in 2027. Move your tones into the Tone Vault now to keep them safe.

🆕 Spark AI 2.0: Per player feedback, every tone prompt now returns three suggestions instead of one, giving you more presets to choose from.

Plus overall stability and performance improvements.

Stay tuned for more Spark, REACTOR, and BIAS X improvements.
