What do the knobs do? Am I missing something or just not seeing the labeling of knob function?
I was wondering that also, they look blank from the photos here. It is screened.
It seems a neat Digital amp. Even Midi controlled for presets.

Quick-Pots
There are five Quick-Pots on Exponent⁵⁰⁰’s front panel (A, B, C, D and E) .
By default, these pots are mapped to the Amp EQ’s four frequency bands and a preset-specific control.
In the Darkglass Suite, you can freely bind the Quick-Pots to your selection of any five controls from the effects in your signal chain.
Preset
Pressing the preset button changes through presets 1 to 5 and a bypass signal. The current preset is shown with a single LED next to the preset number.
When Exponent⁵⁰⁰ is bypassed, all preset LEDs show a dim white color.
Long-press the preset button to start Bluetooth pairing. All preset LEDs will breathe white while pairing is active.
Darkglass Suite
Exponent⁵⁰⁰ comes preloaded with five versatile factory presets. Using Exponent⁵⁰⁰ with the Darkglass Suite isn’t necessary, but we recommend it!
Darkglass Suite unlocks the full potential of Exponent⁵⁰⁰ by providing an interface to interact and modify the signal chain running on each preset.
Use the iOS or Android versions of the Darkglass Suite to create, edit, share, and apply presets. Please make sure your Darkglass Suite version is 4.3.0 or newer!
