My idea: A pickup with a seperate magnet for each pole piece like Wals, but an on-off switch for each magnet. With an 8-pole pickup (ie. a humbucker) it would be possible to have either standard or reverse P, a humbucker on some strings but no on others, or a huge variety of possibilities. I know 8 on-off switches would be incredibly inpracticle, but it would seem easy to say have a 5-way Strat style switch with 5 variations. Is this available anywhere?
