Bartolini NTMB+ FL preamp. This is the 'fretless' version which has a different EQ center for treble.
Bass - ±12db @ 30Hz. Treble - ±15db @ 6.5KHz. Mid - ±12db @ 250/500/800Hz using three-way switch and capacitors per photo. 'Fretted' version has treble centered at 10KHz. I prefer the 6.5KHz.
12db output gain adjustment is very handy for balancing passive and active outputs.
Installed briefly in a Lakland 55-01 using the stock MK-1 pickups. I have used Bartolini NTMB pre's before and knew what to expect. Not disappointed! I bought some Nordstrand BigRig pickups and decided to go with the 'matching' Nordstrand 3B pre as well.
Includes three new 50K ohm EQ pots with center detents. Some wires were trimmed just a bit, but most are original length per photos.
I will include the wiring diagram from Bartolini, slightly modified to utilize a Bourns type M/N blend pot and the Active/Passive push-pull switch option. The M/N blend pot wires backwards from an A/C blend pot.
$75 shipped CONUS.
