This is my replacement for the JS1000. I moved on to the 24 frets and upgraded features. This guitar has some personal history, I bought this guitar in flawless mint condition, but the problem is the thing could not play anything, fret buzz everywhere and bends would choke out, pulling up on the bar would choke out. So I pulled all the frets out and did a compound radius on the fretboard and then re-fret with stainless steel with the hemispherical fret ends. After that it was fixed and now plays amazing.
