I am in love with DGT wire. I'm not sure what it is as far size, but it does seem slightly bigger than MC58, ME wire or the wire used on the custom 24. I have a question into my dealer ( Brian's Guitars) to figure this out. I'll let you all know what I find out.
The other thing to note is that wire used on the NOS ME 1 seems to be something different altogether. I have played 4 of these new NOS ME's and they all have a very different feeling flat top fret wire. It feels like someone dressed the frets on these guitars and forgot to round and polish the frets after they were flat filed. I have been playing the crap out of my new ME and I don't see any fret wear yet but someday I'm going to send it to PTC for DGT Refret. As soon as I win the lotto.
