Description
The NFP is a filter pre-amp alike the ones seen on basses like the Alembic or Wal.
Being a Low Pass Filter, it lets all bass frequencies pass through up to 4 kHz where it forms a
resonant peak and starts cutting after that.
The potentiometer allows you to sweep the cutoff frequency(resonant peak), within a range of
150hz to 4 kHz, and you can boost the cutoff point by pulling up on the potentiometer’s switch
(push-pull).
The NFP was designed to run between 9 and 27 volts and it has a power consumption of +-
2 mAh (@9v).
