So, i've recently discoverd Garage Band on my Mac and my desire to FINALLY learn how to play the guitar. I have a Profile electric guitar that I got for my birthday 20 years ago that I have been playing a little. A buddy, who plays guitar, has offered to get together to teach me all his bad habits. My question is, can I just use my MAudio mobile pre to plug in or is there a benefit to an item like the Apogee Duet/Duet2? I'm kinda geeked out about this new musical journey and I KNOW that this forum will have all the answers.
