The deep, thick "Original Series" voice in the a popular 5 string soapbar shape. A common passive upgrade for active basses. This pickup is very similar to the 72M45C.  The M45C has wider string spacing allowance up to 76mm (72M45C only up to 72mm).   The M45C has 1 x 1 screw holes and the 72M45C has 2 x 1 screw holes.

**FYI - These pickups are packaged only as single pickups by Bartolini. So, if you want to order a SET, you will need to add BOTH the neck and bridge pickups to your cart.

• 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.
