ELECTRIC BASS: APB/GRAVITY/PRO SERIES

The APB/Gravity/Pro Series of bass guitars has gone through several changes over the years. Even though the name has changed and it was advertised as a new model each time, the guitar hasn't changed that much. From 1991 to 1996 the guitars were known as the APB-90 and APB-100. The Pro Series line was used until about 1995. In 1997, these guitars were changed to the APB-4 and APB-5 respectively. This was short lived, and in 1998, the entire line was changed to the Gravity Series. In 2001, the Gravity Deluxe was introduced while the Gravity 4 was discontinued. There is a little confusion about the difference between the regular model and the deluxe model. Several pickup variations have been used over the years, so it is possible that another pickup configuration was used that is not listed here. In 2004, the Gravity Limited Edition guitars was produced.
