Looks darker. Feels better. Sounds stronger.



The exclusive dark look includes a black case, a semi-weighted keyboard with reverse black and grey keys and an even more professional touch feeling. New modulation features and sounds, with a mix of pure synthesis and sampling, push Sledge further than ever before.

New color, best touch.

The reverse color keyboard perfectly matches the black look and thanks to semi-weighted keys and new balanced springs, gives an unbeatable feeling, for a more satisfying musical experience.

Double power, bigger sound.

The audio output level is enhanced, for a stronger, cleaner and fatter sound. The LFO2 is now synchronized, allowing to keep the same modulation phase on all notes.

Sounds from the world.

Top musicians have contributed a signature sound-set which, together with the new settings, further improves the warm and crisp sound that made Sledge appreciated worldwide.
