I'm pretty sure that indeed is Lemmy's first Rickenbacker, which would make it the 4000 thru-neck model. This is the one he had immediately following the theft of the Hopf Studio that he used on Silver Machine, shown here:http://imotorhead.com/forums/ubbthreads ... 19&page=48
It is unclear whether the 4000 bass had the neck pick-up already added when he got it, but at some point Lemmy had a Gibson Thunderbird pick-up installed in the neck position. If you look at the alignment of the four controls, they are not standard 4001 or RM1999. http://www.gettyimages.co.uk/detail/86121730/Redferns
and later with Motorhead, http://www.kotjmf.com/pic/lemmy.jpg
After the Space Ritual tour, he sanded it down, apparently because "it was one of those horrible red ones".
On later tours with Hawkwind he would often alternate between this bass and a Gibson Thunderbird, seen here:http://www.flickr.com/photos/mickymazda/3609038703/
One of his complaints about the 4000 was that the strings would come out of the nut when playing, resulting in it being thrown on stage on at least one occassion.
The modified 4000 again became Lemmy's primary bass after leaving Hawkwind (he has been quoted as saying the Thunderbird was stolen), and history records it was Dave Edmunds who added a metal retainer behind the nut during the recording of Motorhead's first album at Rockfield in 1975.
The bass shows up in many of the early Motorhead videos, for example:http://www.youtube.com/watch?v=bS8Fn2ga ... 4&index=15
As the band's fortunes grew, Lemmy added a white 4001 and later a maple 4001 (stenciled "Born To Lose, Out To Lunch).
Sometime between the Overkill and Bomber tours, the 4000 got broken at the headstock. Sources are unclear as to how this happened, but one report says that one of the roadcrew did it so he could get fired (!). It was repaired, but in the Bomber tour programme Lemmy laments that it didn't sound the same, and he was thinking of having it broken again. Nevertheless, he continued to use it for some considerable time afterwards.
Looking at the video of John Hall with the bass, the neck repair is clearly visible as is the single jack socket (no Rick-o-Sound on a 4000), but at 3:17 there is a shot of what could be where a second jack socket was removed and filled, right under the crack. You can also see the huge cut-out right up to the fret board where the Thunderbird neck pickup was.
I would be very interested to hear any information on how the repair progressed.
Perhaps the next special edition should be a copy of this one?
