Thanks Skinny man for your reply, and the info. I did as you suggested and stripped it down as the neck needed a shim anyway. So feeling a bit of a guitar detective, I took the plunge and offed the neck. Sweet FA unfortunately! I even forgot to see if the truss adjuster was in the neck-end. The body pocket still retained dark brown sawdust and blurred ink markings... nothing really to go on, but it was worth a peek. So I levelled the big jumbo frets and slapped it back up, added the shim and got the neck in true. Adjusted string height, freed up the trem and she was good to go. Trem is unbelievably good considering that I could only loosen the two most important outer pair of screws. The rest are seized solid with rust, but it returns in tune despite albeit careful dive bombing... so that is a bonus.
At the time back along when I obtained the first Strat, Encore were strongly promoting their guitars in many guitar mags. That's when I noticed the now softened headstock shape. This must have been around 1989 and must have as you mentioned, been a new drive under JHS. Even then I didn't know how old this first Strat was. I ended up giving it to my eight year old lad towards his birthday, but told him to flog it to me if he ever sold it as all the newer ones had the naff headstock. That fell on deaf ears. (boys will be boys). So when I saw this identical Strat all these years later, I just had to get it. Luckily it had just been in an older chaps collection that his mate was selling off for his now widowed Wife, and not road worn or knackered. The proprietor of my local guitar shop says that the first Encores were made in India from ash, and weren't bad quality wise. That it plays so well after all these years is certainly testament to that.
Thanks again for getting back to me on this subject.
Cheers and belated happy new year.
Cheers, Col.
