Great thank you these are just the simple adapters i needed work well for my grandson works great excellent works great it works arrived on time i used this to connect to the end of my guitar cable that was going from effects pedal to amp but instead of the amp i plugged it into my macbook pro through garage band i watched a lil youtube vid on how to set the settings to have the mac pick up sound through the linein port and soon enough i was able to play through the mac without a microphone worked as advertised
