Hello Steve (and all the other Tune fans), here an update about my new girlfriend! A month ago she was offered at the internet as a TBJ-41 for 450 euro. I wrote the guy a mail and told him that this was a SB-4 RRS and that I liked it, but his price was too high. Well, the bass is worth that money but the Tune market is not so good (great fot buying one, bad for selling one). Anyway, he wrote me back and said I could pick it up in Amsterdam for 200 euro.
The bass was in a horrible state, it seemed that it had never been polished. It missed one knob and the neck had a enormous backbow so they had set the strings into the highest position, they buzzed anyway. The pick-ups were unstable because of the dried up rubbers underneath it. I decided to adopt this poor one and took it home. I was very worried about the trustrod
At home, I First took the strings of and start to polish the frets and nut with a regular metal polish. Wow, I could almost see myself in the frets, and they are in a good state. Then I cleaned the fingerboard with grandmothers solid dark brown beeswax. I like that stuff, it cleanes, protects and give a nice dark tint. You can also snif it if you dont mind the braindamage

. 90% of the scratches on the body seemed to be scratches in the dirt-layer so after polishing the bass it looked almost new! Wow, what a beauty, I like that colour!
I ordered three new identical knobs, new black pickguard screws, two chrome Gotoh curtpins (there were two ugly gold coloured curtpins on it) and replaced the rubbers underneath de pick-ups. A new set Ernie Ball 3834 (coated bass strings 0.45-100) did the rest.
Now it was time to turn the trustrod
.. A little shakey I started to turn it against the clock, each day a little bit. And yes, it worked!!!!!
Everything is allright now and the Syncron plays very well. I can't wait till my first gig to play it.
I also have two new Bassmaniacs, a TB PSW (well, its more yellow after all those years

) with EMG pickups and a beautifull purple sunburst STB. I can send pictures of these if you like.
Here a pic of my new Syncron (I noticed that they are very rare, not much hints at Google), I'm very pleased with it.
