Tried searching for this and didn't turn up much.
Pulled the Tonegard off my old mandolin to put on the new one, but it's fairly loose. Enough so that it moves around and if I'm not careful can completely fall off while it's not pressed to my chest. Tone gard site says the standard gard fits mandolins with a 9-7/8" wide back, measured the new one and it's just a hair over 9-1/2". Maybe 9-5/8" at the outside. Measured the old one and it clocks in just under 10". The gard was quite snug on that one though so maybe a new one that hasn't been stretched out would work?
Suggestions or experience here? Do I need to fork out for a custom one? I could probably just build up one of the arms with some more rubber and make it work, also.
