Hi all, Im new to DIY recording and I currently dont have any audio interface to record a live instrument to GB. I dont want to plug my guitar/bass to the mic in because i fear that it would eventually blow my Macbook's soundcard. Here are a couple of questions: (1) Can use a DI box (preamp) instead of an audio interface? [bass guitar > DI box > mc in > DAW] (2) If i use the DI and connect it to the mic in, will the bass guitar's signal still use the Macbook's built-in soundcard? or will it only use the DI's? (3) Will DI contribute to send a safe level of signal to the soundcard, thus preventing any harm? (4) Is it OK to just plug in an instrument straight to the mic in? (aside from the fact that doing it will produce an unbalace sound) (5) What are your other guerilla recording techniques that dont cost that much? aside from the line6 toneport , m-audio fast track and the likes.... I dont mind getting a 6-7/10 rating of sound quality as I dont intend to use it for marketing purposes. Lastly, what do you think about this video i saw on youtube: http://www.youtube.com/watch?v=UbZ-UEYqcsE thanks!!!!
