I put these strings on my Harley benton es 335 guitar.
Very cool looking strings, looked nice when i played live on stage, but after a while the color started to wear off and suddenly they were not so cool. Sound of these strings was neat and OK, but did not have a WOW-factor.
The first months these strings are OK for use, but they need to be changed pretty fast, the sound is dull, compared to regular daddario strings.
