As we investigate this whole thing a lot of interesting develoments came to light. When he sings by himself with no mic he seems to have an easier time hitting notes. So we came up with a couple of theorys. He must be hearing something that is throwing him off sometimes, so we are looking at our set up, monitor positioning that kind of thing, vocal effects also. We are also tunning our guitars off the same tuner and I am getting my bass calibrated, maybe he is keying off an instument and we are slighly out of tune with eachother. These little things will only help. And we have our friend coming over this weekend to help in this process and do a real vocal practice with him. Now all we have to do is get him to hit the right notes consistantly.I will update our progress.
