I have recently suffered from a bout of GAS (Guitar Acquistion Syndrome). Fortunatly my wife has cured me by banning the use of e-bay.
However I did aquire two old Harmonys. One a H6659 made about 1973 of birch and a little worse for ware. It has a thinish tone but a wonderful action. The other was billed as 60s vintage American guitar with a split neck joint. This I soon repaired.
It was quoted as a H6850S. Not listed on the Harmony site. The clue to its origin was on the label. Made in Korea! A little research seems to indicate it was made in 1978 by Hondo and fitted with an American built DiMarzio pickup. (unknown by the seller!)
It proved to be the better guitar with a rich tone. The action is high, due to the neck repair, but it is a great slide guitar and the electrics make a wonderful dirty sound. All for £10!
Any Harmony news and views welcome and if you have an old Sovereign you want rid of think of me but don't tell my wife
