I went with what the bass salesman at CMX told me to buy. I didn't even know that Dingwall basses were FF. Now I do. And now I know that their strings are not appropriate for my basses. I didn't even try to install them so I will return them and probably pick up a set of DR Pure Blues instead.@vindibona1 always use a set design for parallel fret basses for parallel fret basses for best results. Use a set designed specifically for fanned basses on fanned bases. Guaranteed success every time both in tone and balance from string to string.
