Just read this thread and it brings back plenty of memories - I still have an EKO 6-string I bought in 1969, and like others above, this was my first 'proper' guitar (I can't even remember the make of my previous cheapo one, long gone, bought for me by my parents as a teenager, on which I learnt to play - I sold it to help get back some of the money I paid for the EKO!). It looks exactly like a Ranger 6 (AFAICT), but predates the use of the 'Ranger' name (which appeared soone afterwards) and has a model number inside instead (it might be J-54 as mentioned by Sandy above, but I need to check - it's something like that). I got it from Ivor Mairants Music shop in Rathbone Place, London (still there when I last looked!) and cost around 30 quid, new (that was a lot of money to me then and it seemed like I was spending a fortune at the time!)

It has a lovely tone, which is what made me buy it in the first place, and is (or was - see below!) very playable with a low action, and has an adjustable truss rod (rare on guitars of that price range at the time, I think?), but as others have said, it's very heavy in construction, and is also not as loud as I would like for a guitar of its size.

I still have it, and occasionally pick it up (I keep it standing near my computer at home, and sometimes pick it up if I want to try something out and can't be bothered to fetch one of my other guitars).

Sadly, it got damaged years ago in a fracas (!) in spite of its robust construction, when it was dropped on a hard floor (not by me I hasten to add). This has resulted in a crack where the top joins the side of the body, at the bottom end. The tension of the strings has probably distorted the top slightly, so it is now difficult to tune properly (I can tune it only approximately). I probably should have done something about it at the time, but I've neglected to do anything about it. I guess I should take it to a luthier to get it fixed, but I suspect it might cost more to fix than it's worth :-(
