My boyfriend is a musician and has been recording music on his laptop using garage band for several years, but he is looking to get into more sophisticated at-home music recording. I'd like to get him something to help him with this goal for Christmas, but I have no idea what may be useful for him. From what I remember, he already has an iRig to record from his guitar to his laptop, a microphone, pretty much every instrument he would want, lots of amps, and guitar pedals. I'm hoping to get him either some kind of accessory to help him set up a home studio, an online class that teaches you how to record music at home, or something like that. If anyone has any ideas that aren't too expensive (around or under $100) please let me know! Thanks for your help!
