Darkglass Electronics Exponential 500 Bass Amplifier Head
Front Panel Features
Use this jack to connect your instrument via a standard ¼” mono cable.
There are five Quick-Pots on Exponent 500’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.

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 e500 is bypassed, all preset LEDs show a dim white color.

Pressing the mute button toggles mute on the physical outputs. When e500 is muted, all preset LEDs will illuminate with a dim red color.
