hi there! sorry this seems like such a silly question - i've been in a few recording studios and all of them seem to have been able to do what I can't, so I know i'm doing something very stupid here: i am trying to record my electric guitar by putting a shure sm57 about 2-3 inches away form the centre of the grill cloth, running it into a Behringer UB1204-PRO mixer, which then goes into my iRiver mp3 player (which records with line-in.) I have been told that you get a good amp sound by pointing the mic at the speakers, but when I do this, no matter how much or little gain I apply at any stage, there is definitely a noticeable hiss coming from the speaker. I think that I am not mistaking this for hiss from improper gain structure , as I have tried nearly every combination my setup allows. It is also not the mp3 player, as I have listened with the headphone output on the mixer, and the hiss is definitely there. I also know that electrical components do give off hiss, however my teacher (who has made very good recordings with me) used the same setup as me: a microphone pointing at an amplifier running into a mixer, with perfect results. am i placing the mic in the wrong place after all? does the amp need to be louder (i use a small marshall 15 watt amp, never tuning it up past the 3rd volume notch) or is there anything else wrong that i am doing? thankyou for taking the time to read this long rant, from me!
