Nordstrand 3 Band Preamps began in 2006, Carey’s evil genius produced these preamps’ design with a handful of goals in mind. They have an informative technical history that occurred somewhat close to the following chronology of invention—ordered as such in order to illustrate the electrical debauchery and collage of component regulated frequency inherent to Carey’s creative mind.
Nordstrand 3 Band Preamp Configurations
The following represent our current versions of our preamps. If you are looking for different options, please contact the shop. Special requests are welcome.
3B – 3 band bass preamp with 3 eq pots
3B-5a – PREWIRED – 3 band bass preamp with volume (pull passive), blend, treble, mid (pull frequency switch), and bass
3B-5b – PREWIRED – 3 band bass preamp with volume (pull passive), blend, tone, push pull frequency selector on mid, and treble/bass stack
3B-4a – PREWIRED – 3 band bass preamp with volume/volume stack, tone (pull passive), mid (pull frequency switch), and treble/bass stack
3B-4b – PREWIRED – 3 band bass preamp with volume/tone stack, blend, mid (pull frequency switch), and treble/bass stack
3B-3 – PREWIRED – 3 band bass preamp with volume (pull passive), mid (pull frequency switch), and treble/bass stack
JC-3b – PREWIRED – 3 band bass preamp with volume (pull passive), blend, treble (push/pull neck pickup – series down, parallel up), mids (1kHz down, pull up for 400Hz), bass (push/pull bridge pickup – series down, parallel up)
*The JC-3b preamp is specifically configured to work with the Dual Big BladeMan pickups in a manner that brings out the edgy penetrating mids and high end character so widely recognized as essential to Justin’s iconic tone. We use a 500k volume pot and the common side of the blend pot is left ungrounded. Also, we have trim pots mounted for each pickups that allow one to balance (turn down) the series output to the parallel output. With all of these tweaks, the JC 3 band preamp, when combined with the Dual Big BladeMan pickups provides a rarefied degree of versatility, delivering everything from the mid forward grindy presence of classic JC tone to a super fat, wide, and deep modern sound with loads of punch.
*All prewired Nordstrand 3 Band Preamps include jack and battery terminals
Overall gain is 0 to 15db by a trim pot on the circuit board.
Bass +/- 12db @ 50Hz
Treble +/- 12db @ 4khz
Midrange +/- 12db @ 1k with no external capacitors. Add two capacitors as indicated in the table to change the frequency.
Nordstrand stock capacitors for the even numbered frequencies and will include one set with each preamp for a second frequency. 400hz is the default second frequency, other frequencies available upon request.
