Thanks for listening guys - any tips on how I should fix the guitars? Is it "EQ-able", or should I just re-record them?
I have to admit, I'm a little strapped on cash (wedding coming up after all) so I mixed the song on $15 computer speakers and a set of Sennheiser HD201s....maybe $100 toward a cheap monitor set would be good?
How much time have you got between now and the wedding?
With the main guitar the boom seems to be between 100h and 200 hz, so you might like to try pulling this area down a bit with EQ. The cause is that this area of the frequency range is probably under-represented on your PC speakers. Pop it onto a CD and listen to it in the car (or anywhere else).
The lead guitar needs a bit of taming. There are three options:
1 slip it back into the mix a bit;
2 give it a bit of reverb to float it and create some space around it;
3 try EQing out a bit of the brightness.
(My choice would be 1 and 2)
Leave your voice where it is. That's what people will notice and is the best part of the song. Let the backing isntruments play a minor role.
I meant to say in my comments earlier that I shuddered a bit when I saw the song you were doing, but I'm so pleased you didn't do the Eva Cassidy version. Not that there's anything wrong with that version . . . that's just the trouble. It's so good that it has become a very common (and therefore overdone) way of doing it. Yours showed a refreshing spark of originality.
Later, when you get more time, I think you should spend the time and effort to work on it and get it really sparkling.
