Author: I need something with the standard guitar amp jack on one end and a USB (etc.) jack on the other end.
Thanks!
On the back of your amp there will be a jack called ‘output’ or ‘AUX out’ take another guitar cable and plug it in there. After that you will need an adapter that goes from a quarter inch jack to a normal headphone jack. Plug that into the mic input of your Mac (Always next to headphone jack). Then proceed to using a program like Garageband or Audacity to record!
