While researching a visual band, I came across one of the members's later bands. When he left that certain band, his role was then described as the "poor/clumsy/awkward" guitarist. Class move, VKDB XDD.
You mean 下手ギター ? It's actually talking about what side of the stage he was on, not about his skill so much. There's 上手 (kamite) which is stage left and 下手 (shimote) which is stage right It's very common to refer to guitarists by what position they are on the stage, at least in VK.
