Designing a JFET Gain Stage Around a Real Part
How to measure a JFET's IDSS and pinch-off voltage with basic tools, then bias a common-source gain stage around the specific part you have rather than a datasheet typical.

The Bench, Written Down
Long-form write-ups of real repair and design work — measured, not guessed. Every article stands on its own; most come with the math and the schematic.

Your Cable Is a Tone Control
Guitar cable capacitance moves your pickup's resonant peak more than most pedals do. How it works, why pedalboard chains compound it, and what a buffer actually fixes.
Building Better Pedals: The Real Role of Components in Guitar Tone
A myth-busting guide to resistors, capacitors, diodes, transistors and ICs in guitar pedals — what each one really does to your tone, and where boutique parts stop mattering.
Why Guitar Pedals Sound Different on Batteries vs Power Supplies?
Why battery-powered fuzz pedals really do sound different: rail voltage and bias shift, supply impedance in the signal path, and the positive-ground daisy-chain trap.
