From my guitar amps line out (it's a little stereo jack?) into our stereo Pa's tape "in" works a treat and somehow gives a sweet guitar sound from around 8mts away.
Fits nicely at each end, not gonna fall out, I hear no sound colouration from using this cable, I also use this at home to connect my MP3 player to my home sound system.
certainly reccomendid for the cost,
