Unless you have played over 20 years, You'll always sound like someone else. My sounds is a combination of Louis Johnson, Marcus Miller and for the pass year or so Andrew Gouche. When I play places 90% of the bass players think I have a unque sound, but the ofter 10% can hear my influences.
Myself, I play like the Bass Player I like to hear. I can make my own groove, but I use their techniques.
