If you are unsure which tip your computer requires, consult your laptop’s manual. Your laptop’s audio-in port may require a stereo plug with a TS (Tip/Sleeve) connection or a TRS (Tip/Ring/Sleeve) connection.You may purchase a guitar cable with a ¼” phone jack on one end and a ⅛” stereo plug on the other end OR you may purchase an ⅛” stereo plug adapter to use with your standard guitar cable. While the average guitar cable has a ¼” phone jack on each end, the audio-in port requires a ⅛” stereo plug.
