Broken H and Triple M, I appreciate the feedback and the kind words.
BH- in addition to the errors, the "raw feel" you mention might be partially be due to this... I tune the guitar and bass until I get nothing but green lights on the electronic tuner, but some songs I've recorded still seem a little out-of-tune to me. Did this sound out-of-tune at all? Maybe I'll buy a set of pitch pipes.
MMM- I have my mixer/recorder set at -9 for 250khz. Could it be possible that I just have the input level for the kick drum track up too high? I have it set so that it redlines even at a kick strength of normal-to-relatively soft. I wasn't sure if it kind of leveled off at some maximum regardless of how high I have it set, or if it starts to affect the sound negatively at redline. I just wanted to cover up those soft kicks I occasionally have due to poor balance, timing, or liquor.
Regarding the guitars- could the muffled sound could be due to the guitar tones I pick? I sometimes get a headache when I pick one that's too bright-sounding, so I tend to skew a little lower. I didn't EQ them at all... do you think punching up the treble on the tracks would be enough to improve it?
I think the muffled snare is due to another one of my recent reversals in habit... In the past I always put enough compression on the snare to make it sound bright, but that really accentuated the bleed from the cymbals into the mic. My new thing is to barely compress it at all. Maybe I could solve this with EQ as well.
I put a little delay and reverb on the vocals which I think causes them to sound a little blurred, but as far as I can tell it evens it out a bit and masks some flaws. Basically, whichever way I record it (with delay & reverb, or with nothing), I always think I should have done it the other way. Not an uncommon feeling for me.
