How'd you rate the fretwork on an Epiphone? If it's not good, is it worth it to get a refret done? Will the frets last as long as they will on say...a more expensive brand model? And if you had fret buzz issues, did a crown/polish job and a good setup take care of it? I know this is an old topic for certain...but it seems to me that this is probably the main complaint amongst Epiphone consumers. Would it be worth it for Epiphone to use more expensive fret wire....??
