"Rosso" free circuit simulator built for pedal/amp DIY
Built a circuit sim that solves the actual physics instead of applying an EQ curve — germanium leakage current that scales with temperature, BBD charge-transfer loss per stage, tube coupling-cap blocking distortion, and more. 1,920 parts, free for personal use (closed source), Windows/Apple Silicon Mac only, amp sim currently disabled (known noise bug). Just added English UI.
