I would agree. The bass pictured, was nothing I had ever seen with SC. However, SC did have a bigsby on his brown alembic. It is possible to confuse the two. However, to prove my point, just google search SC I want to play for you. There, on the album cover, you will see this brown bass with a bigsby.
The real question is: Who came up with the idea first... SC or JE because I don't see many people rushing to go out to drill any holes into their Alembic(s) just for a few tricks with sound.
I put a bigsby on my non-alembic bass, and bending harmonics and sustaining notes were the big push for me to do this. Also, being that I put a bigsby on my fretless bass, I claim to be the first. he he eh
I still want a solid all black shorty in my life time, and the featured bass comes a little closer to my dream bass.
