so i want to hear myself play/practice with garageband and i purchased a pickup for my acoustic guitar for this purpose. it is a woody and has a cord attached to which i added an adapter to plug into my macbook pro as well as with amplitude ap. I do not have an interface setup so this sounded like an easy solution. When I try the connections i get good input but for the life of me cannot figure out how to set this up so i can actually hear myself thru the laptop. ive tried everything reccommended in the Garageband setup including selecting my instrument rather then electric guitar and playing with the output settings but nothing works. starting to think you need a sound engineering degree to figure this out. can anyone help?
