Right, I am trying to record an acoustic guitar through a Shure SM57, which is then plugged into my eMac's line-in jack. The guitar is quite faint, butr what is more annoying is the way the fan noise overwhelms the recording. I am thinking about buying a preamp - WHilst this will solve my faint guitar problem, will it be any use in helping to fade out the fan noise? I have tried fiddling with the effect setting to get rid of the noise, but with little success. My room is quite small, which doesn't help, either. Will a preamp be worth it?
 
is the fan being picked up by the mic?

I wouldn't have expected that from a uni-directional mic like an SM57

also SM57s are only really good for recording instruments where a significant amount of air is pushed. A preamp would solve the faint sound issue but would also boost any accompanying noise. Try looking into a condensor mic for acoustic guitars.
 
I was kindas expecting the same thing from the Shure, but the fan is still there. I found a Behringer preamp for 30 quid, so even if it doesn't work terribly well, all is not lost.
 
Hey,

First off, and you mentioned it yourself, the signal into the audio in jack of a mac is not powered, which is why your volume is so low. Preamps are a must!

More importantly, however, is how close are you sitting to your computer? Make sure when you record you are positioned in a nice, quiet area removed from any background sounds (like your computer). When I record an acoustic with a mic into GB I always leave a bit of lead time on my tracks, to allow me to hit record, move away from my machine to a quiet area, then record my part. I then go back and delete the crap from the beginning of the track where I wasn't recording. Not as elegant as having an engineer in another room hit record while you play in a soundbooth, but the principle is the same!

Cheers!

hehe - i think most people do that, and it's all part of GB magic ;)

Well, I am suck a dumbass! I have been selecting 'internal mic' for my recording method! How STUPID OF ME!!!! Anyway, i tried it with the ACTUAL sm57 input, and whilst is is faint, it is fan-free!

I have bought a dirt cheap Behringer MIC100 preamp on eBay today. I hear these are not wonderful, but they do the job. Has anybody used one of these?

Wowser,

Too bad you figured out about the "internal mic" thing on your own, because I was going to have a right go at you for a minute there! :) I've made the mistake many times myself. I bought a $500 mic a while back and couldn't figure out why it sounded SO BAD for so long. The fan noise didn't even help me clue in, cause I thought the new mic was just that sensitive! ha ha.
 
HAHA - I would be pissed if i thought my new 500 dollar mic sounded like the internal one! I don't think i would even use the internal one for iChat . Can you imagine? : "WHAT? Sorry - I can't hear you - there is this fan noise in the background"
