4-String J-Bass® Shapes
The lengths of the neck and bridge pickups in the original J-Basses® are not equal. The neck pickup is 3-5/8″ long which is slightly shorter than the bridge pickup which is 3-3/4″ long. Some modern designs, however, use two ‘long’ bridge-length pickups. In this configuration it is important to use the “LN” (long neck) pickup that is specifically designed to work in this position (do not use a bridge pickup in the neck position). Some (very few) use two ‘short’ neck length pickups. Please check the physical size of the pickups you want to replace to make sure the replacements fit properly.
Your voice is a combination of your pickups, strings, instrument materials and construction, and playing technique. The voice of your pickups is determined by the sensing structures - the magnetic field projected onto the strings and the interaction of the magnetic field with the coils.
We offer several carefully designed pickups series with different sensing structures so you can develop your voice. Check out the sensing structures below - Blue represents a South magnetic field, and Red represents a North magnetic field. Opposite polarity fields is used for hum-cancelling.
