my recording setup is basically as follows: gibson SG supreme p-90s > line 6 spider 210 > box containing one of the line 6 speakers and a 20$ nady mic > imic (using a 250-50k ohm transformer) > my mac > logic express 7 problem: i am getting very very harsh spikes of various frequencies, usually around 2.5khz details: i have ruled the recording input method out, as i plugged my headphones into the amp and can still hear the harsh sound. that knocks everything out past the spider 210. i can also slightly hear it in the speaker cone when i listen to it up close. i highly doubt it is my guitar as i am getting the spikes from other sources. guitar is not completely ruled out, but theres no reason for me to believe it is the guitar anymore. i also doubt it is the amp, but it looks the most likely. i had this problem also when i was going guitar > zoom 707 pedal > imic, so... what? i even unplugged everything in my apartment wondering if it had to do with something giving off a bad signal. i am so confused right now. sample of the guitar tracks with no logic effects on. the guitar sounds good, but there is a strange harshness that is also showing thorugh. http://nowayride.dyndns.org/music/example.mp3 sample of me touching the end of the cable. the noise is generally what i get while recording. http://nowayride.dyndns.org/music/what.mp3 i havent been working with recording stuff long, but this does not seem normal for a guitar to sound like going straight through. all the EQing in the world will not fix the sound, and of course sharp cuts into the sound just weaken the guitar a LOT. any advise? guesses? anything? forgot to mention... my amp is really messed up. again i doubt this would be the problem considering through the zoom i had the same problem but.. the amp's left channel is fried or something. i accidentally left the amp on one day when i went to school. i came back and it was humming. i plugged my guitar in and only the right side was working. right side has not worked since them. i just ignored the problem and went on my way. i plugged headphones in recently (when i tested the amp) and they FRIED one side. i snapped off the foam and it looked like someone started to burn it with a lighter. first off.. what the hell? second, how could an amp melt headphones, headphone jacks are not suppose to be that strong right?
