I don't know if anybody has ever found any information about the mysterious Sire factory, they claim it's their own facility in Indonesia (and now also China) with their parent brand Dame being produced in Korea and that they don't use OEMs.
I would imagine they do shift decent numbers, I regularly see them on the gigging circuit here and have a few mates who own them. They'll have probably done a small run of the new Godin clones and even less singlecuts but gone big on the Z series, the singlecuts are targeting the boutique on a budget market really and I imagine they'll be able to be heavily discounted and still not make a loss. Hopefully the Godins were a huge flop and I can pick up a GB5-FL when they're at clearance prices!
EDIT: Looking at Andertons they may just be doing batches of the F series based on preorders.
