The Darkglass Exponent 500 is a handy bass top that combines the straightforward operation of a classic bass amp and the extensive sound options of a modern modeling device. “Out of the box”, the Expontent 500 amp offers five presets that can be quickly and intuitively adjusted to personal sound preferences via the straightforward front panel control. In conjunction with the Darkglass Suite app, which the Exponent 500 connects to via Bluetooth, unimagined possibilities for shaping your personal sound are at your fingertips , with not only the order of amp, speaker, and effect modelings freely selectable, but also the routing of the connections within the signal path and the assignment of the knobs on the front. Last but not least, the Darkglass Exponent 500 has an integrated USB audio interface and the possibility of control via MIDI.
