For those of us who are a certain age, -Jet Harris.
One of the very early electric bassists who inspired me to make my first bass, and still be playing nearly 60 years later. Came up with some great bass lines probably derived from his double bass days, and helped to form the sound of the Shadows.
All of these Rotosound endorsers have pushed the boundaries, I mean how can you not think of Mccartney, or Chris Squire, Graham Maby, the Ox etc but for me Jet was the first.
