This instrument is an exceptionally rare, collectible piece of American history. Serial number 90042 dates it to around 1990, but not much is known about these, even in the Mosrite circle. It's an incredibly versatile guitar, capable of anything from that wonderful "woody" surf tone, to speedy country licks, to hard rock. The only reason I'm selling is because I was never able to get used to the narrow Mosrite neck width, and I'm not a collector, so I tend to part with guitars that I don't play. The frets do show some wear, as would be expected of a 20-year-old guitar, but I've experienced no real fret buzz, and it plays just like a Mosrite should: thin neck, low action and easy, fast slides. There are a few nicks on the side near the back contour, and some wear on the arm contour on the top of the body, which I've tried to shown in pics. Other than that, it's in great shape.
It is unknown exactly how many of these were produced or how many have survived, but I have never seen another one in person. The only other one I have found on the internet is in Japan, and according to this site, the serial number designates it as likely one of three. Note that Fillmore, a Japanese company who partly owns the Mosrite name, produced copies of these guitars. This is NOT a Fillmore copy...take a look at the way the neck bolts on, and the location of the serial number. Unfortunately since I did buy this from a second-hand shop, I have no documentation. It is also not signed by Semie, which leads me to believe it may have been built by him, but not put together until after his death, as Semie supposedly signed all his guitars at the time. It may have even been put together by an enthusiast using parts leftover from the Mosrite factory after it closed. However, based on the quality of the instrument and several key features associated with Semie's work, I would say it is undeniably a real Mosrite.
Features:
- Mosrite "Ventures" model body shape with unique Nokie carve
- 24.5" scale length
- 24 fret, 3-piece maple neck with zero fret
- Original Mosrite humbucker pickups
- Mosrite "Vibramute" vibrato
- Side jack
Notable oddities:
- The bridge is from a 12-string model. This does not affect how it plays at all. I actually like it, as it allows for adjustable string spacing at the bridge.
- Tuners are Grover, not the typical Kluson style. I believe this to be original as there is no evidence of the guitar ever having Kluson style tuners.
- There is an engraving on the truss rod cover which says "JEG". There's a "JEG" sticker on the pickguard as well. Little is known about the history of this particular guitar, and I was unable to find the previous owner, but I left these marks on to preserve its original state. They could easily be removed if so desired.
If you know anything else about these guitars, feel free to email me and I will update the auction description. Questions are welcome as well!
then 
but after all that 
Cuz I have no money... thanks for being a tease.
) Perhaps the mystery behind this guitar will finally be uncovered.
