The 4-string Chaos Core 4 is made of paulownia (originally a Chinese tree) and is topped with burled maple or quilt maple. Either way, the Core 4 makes for a lightweight bass that appeals both aesthetically and sonically. To capture your fingerwork, the Chaos Core 4 bass has an Aguilar OBP-3 pre-amp, 3-band EQ, volume. a 5-way switch, and 2 Rockfield humbucker pickups. All the hardware is black and coordinates nicely with the wood grain.
