You can save up to 4 presets to the onboard memory on the Spark amp. These saved presets can be easily accessed anytime you turn on the amp without using the Spark app.
On the top panel of the Spark amp, you’ll find buttons labeled 1 to 4, corresponding to channels 1~4 from the onboard preset slots.
Clicking on any of the buttons will load in the preset saved on that particular preset slot. The LED on the active preset slot will light up.
If you made any modification to a loaded onboard preset, either by turning the physical knobs on the amp or changing the parameter within the Spark app, the LED of that channel will be blinking, indicating the preset has been modified.
By holding down any of the preset buttons, the current guitar tone/signal chain will be saved to the held preset slot. Once saved, the LED of that channel will stop blinking.
