Fletcher Pickups TriSonics
So named, as the U-shaped steel baseplate gives two extra point of magnetic field either side of the coil, broadening the overall width of sensitization.
Combined with a very low wind of very thin wire under a brass cover gives this little pickup a unique voice. Subtleties of the design changed many times over the years.
Mine pay Homage to the most famous set of all!
My TriSonics are scatter-wound with carefully selected wire into Air-Coils,
around vintage correct dual C1/Y10T grade ceramic ferrite magnets.
These are mounted onto a Steel baseplate and topped with a plated Brass cover.
Finished with Grounded two wire leads.

There are Four secrets to a proper TriSonic tone:
Firstly the Bobbin-less 'Air-Coil' wound with thin AWG44. Messy free-standing coil gives that open airiness.
Secondly the duo of Special magnets. TriSonics have used many different types over the years, but these ones are the ones which sound the best to me. Not cheap but worth it. Ceramic, but not like a ceramic in other pickups, these chunky blocks give a reasonably high power, with the resulting bright, quick voice.
Third, the steel baseplate with raised edges to give the three gauss focus point. The steel adds some bass and extra power in, to thicken up the voice a touch.
Lastly, and one I'm at odds with, is the cover. Proper vintage spec is plated brass covers (like a Tele), but I'm a bit partial to Nickel covers without the brass. Brass will trim the top end a bit and smooth out the voice, Nickel will release the top end and the attack,
Low DC and relatively high Inductance gives a bright articulate tone with controlled low end.
Designed to achieve 'That' TriSonic tone.
