Guitar to Computer

[Jonathan Wolfson]

Hi all,

Can someone tell me how to get the guitar to the computer? Right now I
have a port that goes from my guitar to the amplifier, but it is a
thick plug, about one centimeter in diameter! I have no inputs on my
computer that are that big, only inputs that are the size of headphone
plugs! I need some device to enable a big plug to enter a little
socket. Can someone please help me? I want to play guitar onto my
computer without having to tape record myself.

Thanks,

Jonathan
