I'm not sure I understand what you're asking. All p'ups need both a magnet and a coil to work. You'ld never have one or the other. And a "trembucker" simply means that the pole pieces are spaced slightly wider apart to align better with tremolo equiped guitars. That really has nothing to do with magnets or coils.
Indie when you say "albeit strange ones" referring to pole pieces are you talking about a TB-06 or the Parallell Axis Original? A regular TB-06 (distortion) has normal pole pieces.
Gawd....21.3k for the Distortion TB is just sick. I didn't realize that there were 2 seperate Distortions either Artie.
That Blues Trembucker looks like it would be a great pickup. Still vintage output, but wound slightly hot. I've only heard good things about them....I may have to try to pick one up.
Actually there would be 3 if you consider the Original Parallel Axis Trembucker as a Distortion as I beleive it was intended to be the Duncan Distortion Trembucker initially. Then if you included neck variants to the available models it can get confusing. :smack:
