It's a long story but about six years ago I developed nerve damage (ulnar nerve) in both arms, particularly the left arm which required a surgery to relocate the nerve. This ended decades of acoustic guitar playing. If you are reading this, I am sure you can appreciate the pain there and I don't mean the arms, hands and fingers involved in this. I bring that up because after all this time I am now attempting a little comeback of sorts. This is purely for my own enjoyment and I'd like to have some fun creating recordings with Garageband. I am doing pretty good by the way, making progress slowly but surely. I wasn't sure I would be able to but it seems that maybe I can with persistence. So this is not a professional level application we are talking about here by any means nor do I have a budget being retired for that anyway. I'd like to get the best mic for the purpose of recording acoustic guitar and vocals primarily along with harmonica and possibly some percussion at times. That's a tall order for one mic for recording I know but again, this is for fun for me and I'll be happy if the results sound just reasonably decent all things considered. I'd prefer to pick up something from Amazon.com which shouldn't be too hard I'd think given how much stuff they carry from various sources. I'd like to keep the cost to around $100. if possible and if things go well I can consider an upgrade/replacement at a future time. From what I understand, a condenser mic is key for recording purposes. Would any of you guys (gals) have any suggestions for me to have some fun in recovery here? I should have mentioned that I have a late-2013 27 iMac which I note only has an output plug now. I have a pair of Bose desktop speakers using this which have this hockey puck volume control which features sound in and sound out mini-jacks. Am I correct in assuming I need a USB mic for this setup? Thanks a lot. Oh, one more thing. Would this be the appropriate place for questions about Garageband once I start fooling with it or is there another forum where such questions would belong?
