- Needle VU meters with spring-mass-damper physics (analog inertia) - Swappable meter modes: GR needles + input bars, or input needles + GR bars - GR bar meters fill right-to-left (0dB=empty, -30dB=full) - Input bar meters fill left-to-right with green color - Optical cell: normalized parameters (eta=50) for proper audio-level response - Transformer: removed 3-band crossover artifacts, simplified waveshaping with dry/wet mix - Nickel/Iron/Steel with distinct but subtle harmonic character - Layout: optical left, discrete right, meters center, transformer+output bottom center
