Martin Guitars M400 Mandoline Light

I used these strings to replace the factory strings that came with the Harley Benton Mandolin.These strings have the loop ends so in theory should be a little easier to catch on the hooks of the tailpiece end. Compared to the factory strings it was like night and day. Firstly the colour of these strings was so much brighter, nice and bronze, as opposed to dull and grey of the factory. The sound of these was also so much more pleasing. It was definitely a vast improvement, and well worth the money. I would suggest that if you do purchase a HB Mandolin in particular get a couple sets of these strings at the same time. One set to immediately replace factory strings, and one set as a back up..
