Build, simulate, and hear your stompbox before you cut a single trace.
Pedal Bench is an LTspice-style schematic and SPICE simulator tuned for guitar effects. Draw it, audition it through a real guitar clip, then pop out a PCB sized for your enclosure.
Projects
→Your in-progress pedal builds — schematics, netlists, BOMs, and notes, all saved to your account.
Pedal Library
→Reference circuits for classic stompboxes — Tube Screamer, RAT, Fuzz Face, Big Muff and more, with full BOMs.
Schematic Editor
→Drag-and-drop pedal-grade parts: resistors, caps, diodes, JFETs, op-amps, pots. Rotate (R), wire, save.
Simulator
→Time-domain + magnitude response on the active schematic. Tube-screamer / fuzz / boost models.
Audition
→Upload a guitar DI clip — hear it through your circuit before you ever touch a soldering iron.
Tools
→Calculators (RC, op-amp gain, LED resistor, Ohm's law), circuit blocks, debug guides, and pedal-builder lessons.
PedalGuru
→Ask the ultimate pedal expert anything — circuits, components, schematics, mods, and pedal design.
PCB Generator
→Pick your enclosure (1590A, 1590B, 125B, 1590BB, 1590DD) and get a pad-and-trace layout.
Pedal Bench is free for everyone. Upgrade to Pro to remove the AI and audition limits — and to help fund ongoing development.
