Guitar Pickup Theory #6b: Coil shape Part 2 – winding-capacitance

Welcome to part 2. Let us recap the theories we are testing: theory 1) (mostly true) – the shape gives more inductance and DCR per turn, which makes for a lower resonant frequency with a lower Q value theory 2)

Guitar Pickup Theory #6a: Coil shape Part 1 – DCR and inductance

This entry will examine the effect of the shape of a pickup coil on the tone of the pickup, as well as the underlying causes, and provide empirical evidence as support. More specifically, I want to address tall+narrow coils vs

Trash to treasure: converting a wall wart to an audio transformer

I need a 4:1-6:1 tranny that has a flat-ish response from about 100Hz-10kHz to interface a thingie to my computer’s soundcard. A Neutrik NTE4 goes for about $12 and would work fine, but there is shipping and waiting for it to

Guitar pickup theory #5 : shielding, hum-cancelling and flux concentrators

Since I am STILL waiting for my parts orders to arrive, I took the time to run a few tests on shielding materials’ noise reduction in practical situation (i.e., sitting in front of my computer workstation).  This is just another

Guitar pickup theory #2c addendum: pole piece sweep before and after ‘annealing’

So, a parts order that I was waiting for arrived… BUT… it was unfortunately the wrong stuff. That leaves me with a bit of time on my hands, so I thought I would try an experiment that has been in

Coil Winder: Stepper motor traverse mechanism on the cheap

Stepper motor traverse mechanism on the cheap Stepper motors are useful little gizmos, but controlling them is usually a pain in the butt, and all the supporting electronics are too expensive for a DIY savlage-junkie on a shoestring budget, so

Pickup/coil winder update: counter arrived

UPDATE: my counter came in. I took the plunge and bought the cheapest digital counter I could find, and it seems to have worked out, so hopefully this will be useful info: I tested the unit, and it works fine.
