Double NFP MKII

The 'Double NFP MKII' is a filter preamp, for use only with Single coil passive or active pickups (which are 1,4,5 or 6 pole pieces with one large coil wrapped around all those pole pieces, double that for humbuckers) like the ones seen on basses like the Alembic or Wal.
Being low-pass filters, it lets all bass frequencies pass through up to 2.5Khz where it starts cutting. The cutoff point has a resonant peak that can be boosted by pulling-up on the potentiometer. The potentiometer also allows you to sweep the cutoff point(resonant peak) within a range of 100Hz to 2.5khz on the Neck and 200Hz to 2.5Khz on the Bridge.

The 'Double NFP MKII' has one filter per pickup ,offering more tone shaping options, that are actively mixed through the pan/ blend potentiometer and into a Master volume potentiometer.
The Master Volume has a push-pull function, labelled 'Attack', which boosts between 4 & 8Khz . The gain for the 'Attack' function can be set with the 'Attack' gain trimpot on the Blend board.

Atten trim pot: if pickups are too hot, causing clipping, use these trimmers for attenuation. It ships set to 0 attenuation.

Q trim pot: increase the resonance for each filter using these trimmers labelled 'Q'.

Attack trim pot gain: adjust the gain level of the treble 'Attack' function.
