Step-by-Step Guide

*For Windows users: Please install the ASIO driver here before updating the firmware.

*Please try to update the firmware with a different computer if attempts to update the firmware keep failing.


1. Backup your custom presets to the ToneCloud, Spark App or your Dropbox account before you proceed with the firmware update

2. Unzip and launch the firmware update tool. 

*The update tool should be started BEFORE plugging the Spark into the USB port.




3. Turn on and connect your Spark amp to a computer using a USB-to-USB type B cable (we recommend using the one that comes in the box with the Spark amp). Keep in mind that the updater software should be started BEFORE plugging the Spark into the USB port.


4. Click “Connect Hardware” in the firmware update tool 

*If the firmware updater does not detect your Spark amp, please try reconnecting the USB cable on the Spark amp or try a different USB port on your computer. If that doesn’t work, please try restarting your computer and try again.



Once the hardware is detected, click “Check to update”



The app will start updating the firmware. Once the update is completed the message below will appear. Check if the new firmware version number matches the number on the download page.



5. Make sure to update your Spark app to the latest version as well to get access to all the latest features.
