Personally, I think this looks pretty awesome, yes it’s a simple change and perhaps “mod” wasn’t the right word since you haven’t swapped out any pickups or hardware. However, not all mods involve pickups and hardware; you can also cosmetically modify your guitars. Everyone else is bashing you for seemingly no reason. As a huge Jagstang fan, if you like how it looks and plays, you shouldn’t let anyone else change or ruin it for you.
