No battery, no sound
Forget the ground path and it's as dead as a real pedal.
Push in resistors, caps, diodes, transistors and pots. Wire them up. Plug in your guitar or violin and hear the circuit while you build it.
Like a real breadboard, nothing works until the circuit is complete. It runs on the circuit solver from Fuzz14, which matches ngspice to within 0.24 %. VST3 plugin + standalone app with ASIO.
Like the real thing
Floating legs
A part with a leg in an empty row does nothing. Optional hint: a dim dot on the loose leg.
Electrolytic backwards
It works, with a slight crackle and a warning. A reversed battery: "you'd have cooked it".
Short circuit
The battery "smokes" and drains; pull the short and it recovers.
Feedback
Oscillators squeal and motorboat like real ones, behind a safety limiter for your ears.
Footswitch
True bypass: if the circuit isn't wired through, you hear your clean signal.
The parts drawer
Pedal parts only: resistors and pots (real knobs, turn them while you play), film, ceramic and electrolytic caps, diodes (1N4148, germanium, Schottky, LEDs that light up), transistors (2N3904, MPSA13, BC109, germanium PNP) and JFETs; later op-amps (TL072).
Every pot you place becomes a knob on a pedal-face panel you can automate in your DAW. Presets are saved boards: Fuzz14 first, then the classics. Export the schematic and a parts list to build it for real.
The plan
- The solver from Fuzz14, about ten times faster (a Big Muff has four transistors).
- Board to netlist: holes become nodes, strips and wires join them.
- Circuits that won't settle fade to silence instead of glitching.
- The breadboard GUI: drag, drop, snap, wire, rotate.
- The plugin shell, the pedal-face panel, presets, schematic export.
