Alan, want a Gibson 12, try the Elderly music site,vintage & used, then click on 12 strings and scroll down. I tried to make clicky of it, but it wouldn't let me I have a 60s Epiphone Serenader FT208, a small bodied 12 string which I've always strung in concert, and I used La Bella strings for years, I now use Martin strings, but only 'cos I can't get the La Bellas.
Failte.....Giok
