Pickup Set :

Classic Bass soapbars make you sound better, so you play better. They have a rich, deep voice with lots of high-end clarity and warmth. When you dig in, they are responsive and growly. When you pull back, they are clear and sweet. And they’ll take any slapping and popping you want to give them. The Classic Bass series is popular with progressive, jazz, gospel, and metal musicians where articulation is critical. Without sacrificing low-end, Classic Bass pickups are sweat-proof and won’t crackle and thud when you touch them or hit them with the strings.
If you play a wide variety of music, you know you need some pro-level pickups, but you don’t want to do a big upgrade project, Classic Bass pickups are a great choice. They are passive and will work with your current electronics in most basses.
There are different versions for neck (Bass, -B) and bridge (Treble, -T) so they balance well in your bass.BARTOLINI® HR-5.4AP/918 3 BAND, 5 KNOBS (VOL P/P, BLEND, TREBLE, MID +SW, BASS)

Our most popular preamp for decades, the NTMB+F is a 3-band tone control preamp with fully independent Bass, Mid and Treble controls. It is well known to professionals for its very low noise and wide boost and cut range for aggressive control. The voice is clear, transparent, and strong. The treble frequency is set high for maximum available brightness.
A professionally pre-wired and fully pre-tested harness saves the time and aggravation of wiring your preamp and pots into your instrument. Wired with our pro-level preamp and premium audio-quality pots and switches, you’ll have smooth control and be ready for years of rugged use. We include battery clips and an output jack for quick installation. All the pots are grounded with a wire that can be connected to the cavity shield or simply cut away if not needed in your installation. Everything is pre-soldered with pro-quality pure copper wire that is double tin plated and protected with semi-rigid insulation so it won’t flop around in the cavity or degrade over time. We use only professional lead-free solder with non-corrosive flux. Knobs are a personal choice, so they are not included with the harness – except where there is a stacked (concentric) pot, we include a ring knob and center knob since they are not as common.
