The earlly tuners were open-backed.
Unlike the pickups for the 'Artist', which had six individual cylindrical magnets with exposed polepieces (highest for G, lowest for low E), the Sonic pickups had the six holes in the top cover blanked with black material.
Perhaps a Sonic owner could tell us if the pickups have six individual magnets inside, or a bar. If a bar, then the sound of these Tri-Sonics must inevitably be different from the sound of the Artist's Tri-Sonics, whcih begs the question, what is the 'true' sound of a Tri-Sonic pickup?
This in turn brings up another question, which type did Brian May use for the 'Red Special'? There were lots of stories about early Burns guitars being cannibalised for their pickups, but whcih type did Brian May use?
