Hi all! I was hoping that I could just plug my jag into my macbook pro's audio input and record into garageband. Unfortunately, the signal strength is too low to be favorable (I kind of knew this going in). I so have a radio shack stereo pre-amp (that I've used for my record player) sitting around. If I were to add this to the loop would I blow up my mac's input, or would this work give me the signal strength I'm looking for?
