If you are uncertain whether your guitar uses short (3/8") or long (3/4") shaft pots, as a general rule this pot will fit most USA-made Gibson Les Paul's manufactured before 1977 and historic reissues, but please double check before you order. 2. Make sure to pinch the tip of the shaft before you try fitting a knob, this will avoid getting knobs stuck before you install the pot. If you've ever had that happen...
