No story behind it--my name's Jon Fine, so, jfine. Not very imaginative, but it works. I'm known by that name on several other guitar and amp forums. Back in my road days in the '70's, before there were cell phones, we used CB radios (anybody remember those?) to communicate on the highway--my handle (CB nickname) was Kosher Cowboy (!). "Kosher" because I'm Jewish, although my family didn't keep kosher, and "Cowboy" because I was playing mostly country music at the time, although I've never actually been a cowboy. I suppose I could have used that for a forum name, but I'd just as soon leave it in the past!
