"Fear not, for I am with you; Be not dismayed, for I am your Guitar God. I will strengthen your truss rod. Yes, I will help you stay in tune, I will uphold you with My righteous right hand volume control. I may however have erased your details." From the Bible for Mad People: The Book of Pointless Incantations, Chapter 66 Verse 6.
Yes, it's guitar serial number check time again, brought on by a slight de-cluttering of the mind and the physical storage spaces, not quite a death clean. Delving into the depths, digging deep, some reorganizing coupled with a little painful research. The interweb and eBay don't yield much and the old forums have collapsed in some bizarre way, possibly replaced by Facebook groups or something darker or now completely underground. Perhaps there's just an old shoe box full of notebooks on a shelf in a dusty cupboard dreaming of being a searchable database some day.
So I'm excluded from the greater body of knowledge, excommunicated. It's mostly down to the record keeping failures and glorious demise of the various guitar box-shifters and makers of the 70s and 80s that plied their trade between Japan/Korea and these septic isles.
The Samick factory controls and produces 80% of the produce but their serial number systems are either non-existent or incomprehensible, there's no halfway measure here and the trail goes cold. Valuations are therefore not much more than a wet finger in the air, but at least the air is fresh and never mind where the finger might have been. It's no way to make an honest living.
