Hey all

 

So here's another unique preamp. If you're looking at this, you probably know what it is already - a filter-based preamp.

 

I've documented the sound of this well over at my Youtube channel, and perhaps some might be familiar with it through that. One video showcasing it is at https://www.youtube.com/watch?v=gAMnqz6Uoic&t=85s

 

 

It can be used with any type of pickup, unlike the 'Special' version. 

 

Since I've now upgraded to the Mark 2 version of this preamp, I don't need the Mark 1 version anymore. 

 

This version doesn't have a pick attack/treble boost switch or variable Q filters of the Mark 2, though it remains excellent nonetheless. It has slightly wider frequency ranges for the pickups as a result. I've copied the original sales blurb for ease:

 

'The Double NFP is an onboard bass preamp. Unlike common EQ/Preamps, the Double NFP allows you to completely change the character sound of your pickups by shifting its signature resonant peak. This, plus the ability to actively mix them, gives you a full new level of exciting tones not available on regular EQ preamps.

 

The Double NFP is a filter-based preamp alike the ones seen on basses like Alembic and Wal basses.

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.

Being a low pass filter, it lets all bass frequencies pass through up to 4Khz where it starts cutting. The cutoff point has a resonant peak that can be boosted by pulling up the potentiometer. Each Filter potentiometer also allows you to sweep the cutoff point(resonant peak) within a range of 150Hz to 4 khz.

 

Specs

Sweepable Filters Range: 150hz to 4khz
Resonant Peak (Q): +3db standard/ +6db (boosted)
Operation: 9 to 27volts
Current Draw: +- 4.5 mAh
Dimensions
Filter boards x2: W: 3.3cm; H: 2.3cm; 😧 1.7cm
Potentiometers: Hole size is 6.35mm, and bush height is 10mm.'

 

It's fully working, as you would expect.

 

Happy to sell for £107 + shipping in the uK.
