Description
The ‘Double NFP MKII’ is a filter-based preamp alike the ones seen on basses like Alembic and Wal.
This updated version has a new feature, labelled ‘Attack’, which consists of a Boost of a narrow set of Treble frequencies accessible via a push-pull switch on the Volume control. There is a Gain trim-pot, on the Blend board, which allows for boosting the ‘Attack’ level.
It features one filter per pickup, offering more tone-shaping options, that are actively mixed through the pan/blend potentiometer and into a Master volume potentiometer.
Each Filter potentiometer also allows you to sweep the cut-off point(resonant peak) within a range of 100Hz to 2.5khz, on the Neck, and 200hz to 2.5khz on the Bridge as well as boosting their Resonant Peaks (Q) by pulling up on the Filter potentiometers.
