I still have doubts about the pickup. First of all, I think the promo video does not sound close enough to an original bisonic, even though there are some similarities. Like me, they play through a Bassman. I am familliar with the combo Bassman+bisonic. I don't think it has to do with the recording. That does not color the sound enough to make it unrecognizable. It might be the strings. I have had rounds on my Guild, but there are rounds and there are rounds...
But the thing that feeds my doubts the most is how they promote it. If I were in charge of the promotion at Guild, I would do anything to clear away any doubts. They should know very well people have doubts, after all, the standard of the industry is not to make authentic remakes but to make "modern interpretations". Buying a new Fender Stratocaster is not the same as buying the guitar Hendrix played, and Gibson can't even make a descent PAF or mudbucker these days. So, if it is a genuine copy of the original, Guild should be very interested in letting everybody know precisely that. I would state loud and clear it is a genuine copy, I would have promotion pictures of the pickup out of the bass, and I would give details such as kOhm, magnet type and so on. And I would also state clearly it is a copy of the Hagström bisonic and not a copy of the Darkstar. After all, what many, perhaps most, people like about the SF is not the bass itself but the pickup. The post-69 Guild humbucker version does not have the same vintage value, and it is not associated with Casady, Lesh and Alembic.
Also, seeing as Fender owns Guild, if it is the genuine thing, I would also make a Fender Berry Oakley Sig Tractor bass and launch it at the same time as the SF.
So, the question is, are the people at Guild really this bad a promotion? Or do they not have the genuine thing to promote?
That said, I sooooooooo much hope this is the genuine thing. It would be the best news ever. Only a genuine remake of the Gibson LP Triumph could come close. (Not that I need any of those two seeing as I have vintage ones already).
