Sorry, but I don't know what other info to give.
I have soloed it, which is how I discovered the issue. I recorded it a while back and am in the process of mixing.
It seemed fine a couple of days ago, but when I soloed it to check it out, I heard some distortion.
I also had compression on the track but had to turn it way down from where I had it originally because it no longer sounded as clean.
I did not record it too hot, btw.
