Wiring guides. Pickup simulations. Tools.
For musicians who make things.
Started with a question about pickups. Ended with a circuit topology nobody’s documented for bass.

I Simulated 29 Jazz Bass Pickups So I Wouldn't Have to Buy Them All
Python pickup simulator ranks 29 Jazz Bass pickups by brightness. Seven with measured RLC data, the rest estimated. DC resistance is the wrong number. Inductance predicts tone.

Jazz Bass Master Harness: Volume · Q · Blend + Series/Parallel + Phantom Buffer
A Jazz Bass harness with series/parallel switching, a passive Q-filter resonant boost in place of the tone control, and a phantom-powered ring-hot buffer. Three knobs, no tone pot, cable-immune. Built for Fralin Split Jazz. Every solder joint numbered.

The Q-Filter Build: A Passive Resonant Boost That Replaces the Tone Knob
A Jazz Bass harness with no tone pot. In its place, a passive resonant boost — a 50kΩ reverse-log pot and one cap to ground — that lifts the Fralin's resonant peak +6.9dB at 1165Hz. One knob walks the bass from J to P.
