well i was trying to restring my guitar for the first time on my own, and i bought new ernie ball heavy bottom gauge 10-52

i have a tanglewood strat copy and where the e string (the lowest sounding e) meet the fret board (the white bit where the string is supposed to sit) it doesnt fit in and it like on top of it and when i play a song if my finger is a little near the fret marking (metal lines) it has an awful buzz, can anyone help?

yeah get the slot cut, but make sure the string fits nicely in. if its quite tough to get in you could end up breaking the nut
