Strengths

  • A genuinely boutique-grade Swedish-built semi-modular synth, prized for exceptionally clean, precise analog circuitry
  • Dual filter design gives real sonic range from subtle warmth to aggressive resonant sweeps in one self-contained box
  • Self-contained design (no separate case/power needed) makes it considerably more approachable than a full modular system

Trade-offs

  • Extremely limited production runs from a small manufacturer make used units genuinely hard to find
  • Commands real boutique-tier pricing despite its compact, semi-modular (not full-system) scope
