Not to start another Low G thread, but I recently acquired a new soprano with the Martin style bridge and I am wanting to try a low G for it. I am wondering how this will work with the "standard" style "tie a knot in the string" bridge slot. I'm thinking this will not work well with a wound string, and I don't think a wound ball end string will work well with this type of bridge. I have read that there are some non-wound, smaller diameter, higher dense low G strings available? Perhaps the Aquila Red? Are these thin enough to tie a knot? Any other brands? Any other suggestions? Thanks!
