Bartolini 9J1-L/S 4 String Hum Cancelling Original Series Jazz Bass® Pickup Set

Full and warm deep vintage tone - Bartolini's most popular dual inline-coil hum-cancelling Jazz Bass® upgrade pickups. 

The original Bartolini design gives you the timeless tone that started it all – full and warm for that vintage voice you've been craving, enhancing the natural voice of your bass. These dual coil inline pickups are hum-cancelling even when only playing the neck or bridge pickup, so they are well suited for studio or stage. They have a blade core design, so you don’t have to worry about string alignment. Original Barts bring out your voice, low and clear.

In the early ‘70s, Bill Bartolini leveraged his deep knowledge of acoustics to create pickups that produce the most natural, musical voice from the instrument. He added shielding to block radio signals and noise. He developed a method of sealing, isolating, and stabilizing the coils so they could be encapsulated in epoxy to eliminate “microphonics” – the nasty noise you get when you touch typical pickups.

Available in balanced specific bridge and neck versions.

Below are some general impressions and anecdotal thoughts gathered over the years about Bartolini's Original Series. Some are our own and some are from customers.

• Most players will hear these pickups as giving their bass a fuller tone, typically a very significant improvement over stock pickups.
• While the tone is not vintage, the Bartolini Original Series pickups are  on the warmer side of the spectrum.  These are not the pickups for you if you are looking for a bright or airy top end.
• Regularly, players will comment that these pickups fattened or thickened-up the tone of thin sounding basses.
• Output is medium, some see it as a bit quieter than others.  Having used these a lot, it isn’t as if these are uber-quiet, but you may need to turn the master volume on your amp a bit, depending on the rest of your signal chain.  
• Bartolini’s corners are nice and rounded over, so if you play with your thumb hooked on the top corner, these will probably feel a bit better than a traditional pickup shell (referring mostly to Jazz® and Precision® Basses.
