Behind the guides

CircBench editorial

Project guides based on CircBench's reviewed circuit examples. Results are simulated unless explicitly identified as physical measurements.

This is the publication's organizational byline. It does not imply a separate accredited laboratory or a physical test of every project. Read our editorial approach.

Project guides

stripboard · intermediate

Bias and build a two-transistor fuzz on stripboard

Trace fuzz bias, run modeled waveforms, and build a checked vero layout with three essential track cuts, exact wiring and step-by-step screenshots.
