SOUND CHARACTER:

The SpaceBass excels at punchy bass tones, atmospheric pads, evolving textures, and experimental soundscapes.

*The fretboard is split into 2 sections, called Controller A & Controller B. Controller B provides immediate, unprocessed bass attack perfect for rhythmic playing, while Controller A offers lush, effect-laden sounds ideal for melodic content. The combination creates a powerful performance instrument with incredible sonic range."
