Just put my 1st set of flats on my fender J V. Ernie Ball 45-130 and the "B" didn't fit through the ferrule. I had to peal away a bit of the fuzzy string to get it through. Just wondering if this has happened to anyone? and did I compromise the string by taking away a little layer of the fuzzy string cap? fwiw this is the 1st set of flats i've ever had on a bass. seems pretty awesome. can't crank the amp up this late but just playing feels like a dream!!
