I have a string on my bass which is noticably lower tan the rest. It is the smallest string (i have no idea what its called because i play tabs and i cant remember which top sting or bottom string is either the string that is physically at the bottom or the lowest) anyway, i have tried a 2 mm alan key, which is too big. I think that it is either 1.5mm or 1mm, but i am not sure which. does anyone know which one is more likely, and where I can get it from her in the UK?
just noticed, loads of whiches in that, sorry
