Used Lusithand Double NFP MKII Preamp W/Knobs

I bought this system about a week ago and have decided to go a different route.
New condition. In Box. With 3 Lusithand 1-10 knobs and 1 Neck-Bridge Balance knob.
I paid $315

From Lusithand:
Our ‘Double NFP MKII’ filter preamp consists of two Resonant Peak filters, one for each pickup, that will totally flip your Bass game around.

You can set the filters to very different frequencies and mix them together using the active Blend control to achieve unique and personalized tones that regular preamps wouldn’t allow.

!!!These preamps are compatible with Passive and Active Pickups!!!

New Features:

Treble ‘Attack’ boost via Push-Pull on Volume potentiometer
Neck: 100hz to 2.5khz; Bridge: 200hz to 2.5khz
‘Q’ variable gain on top of the set gain levels
Longer battery life and lower noise level


Resonant Peak (Q) +3db standard/ +6db switched (boost accessible via Q trim-pot)

Operation 9 to 27volts

Current Draw +- 2.9 mAh
