If that's his main one, I believe it's had the headstock put back on a couple of times
I've got a couple of Tom's former basses....ironically, two that are related. The "Busted" album Hamer 12-string with the album graphic on the front & back and "BUSTED" inlaid down the neck (it's a rare medium scale with a maple fingerboard!) This was supposed to be in a music video for the album but didn't get to the shoot in time, so Tom decided to use....the other bass of his that I happen to also have...his Hamer Thunderbird 8-string one-off. He also used this 8-string when he toured with Concrete Blonde and did TV appearances with them around 1990-91.
Both have the standard Petersson three quarter-inch jack outputs and three toggle switches, so each pickup goes to a separate amp and can be turned on/off.
