The body is obeche, with synthetic moulded wings to keep the weight down. The layout of the Collision is just like the Fender Precision Bass. There is also a push/pull tone knob that functions as a serial/parallel switch. The neck is made from one piece of maple with 20 well finished medium frets, and a "skunk stripe" on the rear.
