When you do a google image search for Justin Meldal Johnsen, you get images of JMJ playing various basses but quite a few feature him with his blue mustang or his signature fender model based on his original. Similarly an image search for Jack Casady returns a lot of images of Jack with his signature Epiphone semi in various colours. However a search for Marcus Miller returns a lot of pics of Marcus with his '77 Jazz and/or the Fender signature based on his '77 but no images of him with the Sire basses that carry his name. Does he actually play them? If not it seems an odd endorsement. Or am I missing something?
