I have rarely if ever posted in this forum, so please forgive me if I am asking anything stupid! I have an old 60's Klira Bluebell 12-string acoustic, purchased from a thrift-shop for about $35. I worked on it a bit, and it plays reasonably well. The top is a bit bellied. The bridge is string-through for ball-end strings - it does NOT have pins holding the strings in the body. I just had an idea that I could convert it to a Bajo Sexto, at least for learning purposes. I have found Bajo Sexto strings on line. They have a "loop end", which I know from pictures and ancient memories of mandolins. But my memories are cloudy, and my current knowledge is vague. So my first question is: does anyone have a good method for using loop-end strings on a string-through rosewood bridge? I am wondering how you would anchor the strings so the loop-end doesn't pull through the hole. My second question is - has anyone ever tried this conversion, and if so - does it work? Am I liable to run into any unforeseen problems?
