The W125-001 is a lightweight aluminium Telecaster style electric guitar.

This guitar is inspired by the 1930s Mercedes-Benz and Auto Union grand prix cars. These cars were famously known as "Silver Arrows" because of their raw aluminium bodies, and incredible power and speeds at which they ran.

It is particularly inspired by Rudolf Caracciola's W125 Mercedes-Benz used during the 1937 German Grand Prix, which used the number 12; and finished first ahead of two other silver arrows cars (Mercedes teammate Manfred von Brauchitsch, and Auto Union rival Bernd Rosemeyer), which completely destroyed the competition by finishing over four minutes ahead of the field.

The W125-001 features a wooden body and neck covered in aluminium; hand cut and shaped aluminium control plates, pickguard, knobs and pickup cover (which holds two single-coil pickups); and special spanner screws (which are the same tamper proof screws that were used on the original silver arrows race cars). The neck has been hand painted to imitate a dull and very dark petrified wood that contains mostly carbon. The strap is 100% cotton in white, in style of the drivers uniforms used in the 1930s.
