Again.. Alchemist and I agree here. Less reverb on vocal ...yes...bu try doubling the vocal...yes 2 seperate tracks...and use various effects on each track....1 slight reverb...2nd slight delay...maybe even a soft flanger to cover intonation problems with the voice. It may help. As to the guitars....Jammin on the pentatonic scale in a song is gr8 if you've got "chops". I suggest you actually work out your leads before you record...that includes the leads on the out as well.
