I have played classical and flamenco guitar for many years and always fitted new strings the conventional method and tucked each string underneath the next one at the bridge. This always took me a very long time, up to half an hour and the problem was, if you broke just one string you would have to untie the others to remove it.
I had seen these String Ties advertised at Thomann and thought, what a waste of money.
Then, quite recently, I ordered a few things from Thomann and needed to spend about 5 euros extra to get my free shipping, so I ordered a set of these String Ties.
When it came to replacing my old strings, I decided to use these as a trial.
I was surprised how easy and quick they were to fit. Less than half my usual time. They also looked extremely neat and tidy and should I break a string it will be so much easier to change. I would recommend any classical guitarist to try them, professional or beginner.
