In this video I discuss Tri-Sonic pickups in depth. Join me as 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.
Please also check out part 1 of this two part video series in which I discuss and make a replica of the home made pickups that Brian May originally fitted to his Red Special guitar before he changed them to the Burns Tri-Sonic pickups used in all Queen recordings and stage performances:
