I've been using these strings on an old Stahl single 0 guitar, made in the 30's or 40's. It's ladder braced, and probably originally came with nylon or gut strings. Steel strings have too much tension for this guitar, so the lower tension of the MA130 is a great compromise. I just wish they offered a coated version, because the wound strings go dead fairly quickly. If anyone knows of a company making coated silk and steel strings, please email me at
