The Double NFP-Special preamp is an evolution of the Double NFP but designed specifically for Multicoil pickups that benefit from a “one humbucker per string” coil wiring, simulating Wal MK electronics. The idea is to get a full Humbucker pickup with one pair of coils per string combining them electronically for minimum loading effect and string isolation. This method of mixing the coils brings maximum output, clarity, and punch out of the pickups without any adverse loading effects.
The filter controls have now been updated with a sweepable resonant peak that ranges from 100hz to 4 kHz on the Neck and 200Hz to 4kHz on the Bridge. You can also boost the cutoff frequency(resonant peak) by pulling up the potentiometer.
It offers 6x inputs so that you can wire any multi-coil pickup up to 6 strings.
