correct me if I’m wrong I've had this discussion with mica and others, alembic's pickup strategy isn’t low impedance, its low magnetism. they use a pickup with a low magnetic field so as not to dampen the strings in a magnetic field, but to let them vibrate freely and then run it through amplification. the low impedance if it needs to be recognized comes later in the buffering, which by the way is buffered twice sending and return. it's just that referring to the pickups as low impedance as if that is its strong point may be barking up the wrong tree. again a simple posting of this on the alembic site would yield tons of useful information

This is true to a certain extent, but they did experiment with low impedance pickups. My '73 Series pickups are around 800 ohms or so. that's pretty low. It's also got low magnetism. The preamp card is crucial with these pickups, which do seem to sound different than other Alembic Series pickups I've played. The low end seems clearer and deeper. My understanding is that the newer ones are more correctly designated medium impedance.


hi '73 by any chance do you have the dummy load/pickup in the middel for noise canceling?

I mean the only thing i can see low magnetism doing would be increasing sustain... not only that alnico magnets don't have too much pull anyways. i could be wrong
