Current-Loop pickup.
« on: April 11, 2017, 01:34:45 AM »
Not much work for a CNC machine here but I have to establish just how ‘clean’ the signal from a ‘curent-loop’ pickup really is and exactly which parameters are being controlled by the design. It’s early days yet and more prototypes will be on the way.

I appreciate that Lace have the patent situation well under control but there is always a loophole or two (Dyson have more patents on their Cyclone than I have made posts on this forum but it has not halted the ‘march of the clones’).

Interesting stuff Tweakie; you are into a bit of everything!  I haven't played for years but really miss it at times.

Dummy me had never heard of that type of pickup but Mr. Google soon educated me.  Cool stuff!  If I get a pickup like that will it make me play like Tommy Emmanuel? ;D

Hi DB,

I made that prototype just thin enough to slip beneath my strings alongside the neck p/u - Unfortunately, it did not improve my playing one bit  ;D ;D ;D

Obviously all the existing patents documents need checking in detail but at first sight “The primary winding is magnetically coupled to the secondary winding by high magnetically permeable metal laminate core elements” does not apply to this design which utilises a toroidal, ceramic / ferrite core. This could be the loophole I am seeking.
