Hey, I am recording stereo acoustic guitar. The only mics I have are a Shure SM57 and a Shure SM58 - so im using 1 near the 12th fret and 1 near the bridge. Trouble is I need to turn the gain right up to get a decent (loud enough) signal with these mics, but then I also get a lot of noise (hiss). I dont notice the hiss when singing into them, only when doing quite stuff like acoustic guitar (singing is lounder and more directed I guess). It doesnt seem to matter if I turn the gain up on the mixer, or in my recording package the hiss is still there. Would you expect this hiss with these mics (im going into a Presonus FP10) in which case maybe I should get 2 small matched condesors? Or would you expect their to be very little hiss in which case I should look to fix the problem (maybe I have a dodgy FP10, but I dont want to go down that road unless im certain its not just the mics). Thanks, AM.
