Couple of months ago i changed the strings on my electric guitar for the first time, said axe was about 13 months old at the time (know i should do it it more often but new guitarist etc etc) and i noticed grooves worn into the first and second frets! (explains the string rattle i'm getting) today i changed the strings on my acoustic which is 10 months old (see, i'm improving) and thats the same!! now i know fret wear is an issue on guitars, but at this early stage!?! i just kinda thought it would take longer, is this normal? or have just got el-cheapo fret wire on my axes??
