I did read the article and had a smile when he is quoted as saying it can do everything the alembic does.
However, we know from his touring photos that appear on line and reviews by us after attending his concerts, that he is seen more with his Alembic than spellbinder so.... I guess the proof is still in the pudding,
I think I have seen him with the spellbinder twice, once he played it virtually all night and had the alembic and upright bass behind him waiting patiently and the other one he played his double bass mostly. But in more recent years I have seen him only with his Alembic and Double bass.
