This is an interesting bass.
Here's the scant details from the original build card:
serial number: 75-174
model name: Series I*
model number: LSBI4
top: Zebrawood
accent: none
body: Mahogany
back: Zebrawood
neck: Maple (only wood recorded, but pictures of Andy West with bass show darker laminates in the middle)
scale: 34 long
fingerboard: Rosewood
inlays: Abalone
originally made for: NAMM display (don't know if 1975 or 1976)
birthday: not recorded
OK, so we know from the history that Andy West posted
here that he purchased the bass from Charlotte's Reliable Music, who we must have sold the bass to at the NAMM show.
In 1980 Andy sent it in to have the peghead repaired and the frets dressed.
In 1981 Andy sent it in again to have the peghead repaired. We also repaired the power supply as the thermoprotector needed replacing.
There is an undated note with the synthesizer wiring:
1-black
2-red
3-orange
4-blue
Which explains the second XLR housing and the holes on the front where the pickup was previously mounted.
In 1985, the second owner of the bass had the whole neck replaced, keeping the original body. This was recorded as 5-piece neck, which is typically maple and Purpleheart. He also had us leave the fingerboard black because he was considering a custom inlay, which he apparently had us do (though it's not recorded, it looks like our typical Tree of Life design).
Whew! The other little note is this bass has the top from The Zebrawood a massive board with Bird's-eye figuring and wiggly flames here and there that we made a lot of guitars and basses from.
*Calling this a Series I, though technically these model names were not yet established.
