Baz does GREAT work.....I've had SIX of his builds!!!!
And Jeff has, three Hamer 12vers, I believe. A one-off DuoTone Bass version. That's the Hamer guitar model with a piezo bridge and a hum buckler, so you can switch between electic/acoustic or combine them. Jeff had a bass version made but I heard it was with mixed results.
He also had his B12A "Jeff Ament" model. Plus I sold him another one that I had that had a pao ferro fingerboard.
He also had a Hamer 8-string B8A that he did his own custom graphic on and then, I believe Hamer clear coated.
Plus he has that oversized TBird body that Mile Lull made, with a bolt-on Hamer 12ver neck.
When he had that one made, he told me that he still had his Hamers.
Hamer really DOES make the best 12ver necks hands down!!!! Stable dual-truss necks with decent neck profiles. It's a shame Hamer wouldn't make those necks separately and we have to keep destroying complete Hamer 8- and 12vers to steal the necks and hardware....but I've never liked their Chaparral,body shape, so sticking them onto exact copies of Hamer TBird bodies is a definite improvement IMO. Hamer "improved" on the TBird design by moving the neck joint out a couple of frets and then thickening up the body for a little more weight, for better balance. I think the cutaway is slightly larger for easier access as well. They had a prior relationship with Gibson, so they didn't get sued back when they were making them, like so many other companies did who made Gibson-ish designs.
