We always craved a clean head. A device that is “out of the box” is an amplifier without added effects. Uncomplicated, intuitive, and for each one of us to be able to unveil the layer of sophistication that better serves our projects and skills. The Exponent 500 is a new concept that once connected turns into a multi-effect, with fully programmable and presettable signal chains with all the components a professional bassist requires.

Front Panel Features

Input

Use this jack to connect your instrument via a standard ¼” mono cable.

Quick-Pots

There are five Quick-Pots on Exponent’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.

Master

Use this knob to control the overall volume of the amplifier.

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 Exponent 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.

Mute

Pressing the mute button toggles mute on the physical outputs.

When Exponent is muted, all preset LEDs will illuminate with a dim red color.

Darkglass Suite

Exponent comes preloaded with five versatile factory presets. Using Exponent with the Darkglass Suite isn’t necessary, but we recommend it!

Darkglass Suite unlocks the full potential of Exponent 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!
