Tri-Sonic Pickups: General Information, Brian May Red Special Pickups, Coil Winding and Assembly

I made the embedded video below in June 2022 to accompany the FAQ on Tri-Sonic pickups. It is 22 minutes long and covers Tri-Sonic pickups in depth. I take a look inside an early 1960s vintage pot magnet style Burns Tri-Sonic pickup and compare and contrast vintage and modern variants. I discuss the characteristics of the specific set fitted to Brian May’s Red Special guitar with reference to a replica set made by Ade Turner of Adeson Pickups.

I demonstrate two methods for engraving the chrome plated brass cover then wind a bobbinless Tri-Sonic style coil on my Stepcraft 2/840 CNC machine using a custom made former to my own unique design. Finally, I assemble all the component parts of a Tri-Sonic pickup and measure its DC resistance and inductance using a Peak Atlas LCR45 meter.

I have written a short (<1,500 word) article intended as a primer on Burns Tri-Sonic pickups for general interest within a Brian May Red Special context:

The article is illustrated with a number of original photographs, CAD renders and a few ‘library pictures’ like those depicted below:
