bass two
Hamer 12 String (Purchased during recording of "Ten", Jeff wrote "Jeremy" and "Why Go?" on it. It seems to be his most popular 12 string)

bass three
(mike lull guitars)
"Big Brother" a 90's Hamer Cruisebass with 2TEK bridge. Jeff ordered these with larger headstocks than the regular production Cruisebass. Hamer has a sample of his neck (with the big headstock) at the factory in their artist neck specs rack. For some reason, Hamer was building two of them. Jeff had only ordered the one, which is believed to be the "Big Brother" one. Hamer would shoot the basses in white, send them to Jeff, who would do the artwork, send them back to Hamer for the final clearcoats
