Well right now, I have a line 6 and a mac, I use the pod style head phone out, and use a head converter, then a headphone cable to my audio in on my mac, I use garage band to record it. It gets fairly good sound but i just feel like it has a small speaker sound. I was wondering if there is anyway possible to record guitar a little professional without a mic, and If i need one, what would be a decent mic for getting a professional sound. I also heard about cubase like you can use usb to record but I'm not sure about that. Is there anything else possible without a mic to get a better sound?
