I have one, it was on, and I even sang sideways into the mic. It may be something about the way I sing, or something. Never figured out how to get it any better.

wow - that is unusual. If you don’t mind me asking, what kind of mic are you using?

In this case, an SM-58.

when you said, that the pop filter was on, did you mean the internal little foam thing under the rounded wire-mesh housing of the sm-58? Or were you talking about an additional external pop filter placed a couple of inches in front of the mic?

In this case neither, but something like this:

Actually, that’s usually called a “windscreen”, which is different than a “pop filter”. Windscreens can help outdoors in the wind, and can be good enough for lower fidelity situations (live gigs etc.) or with radio speech, but not so much for the higher quality needs and often more serious air-flow of singing.

You may want to try something more like this. That page also has ideas how to make your own, if you’re more of a DIY person.

And make sure, it’s far away enough from the mic, otherwise it doesn’t help much. And with the pop-filter sing straight on into the sm58 - that way you catch the sweet spot of the pattern of that mike.

Of course, if you’re ever getting more serious with your recordings and your music budget allows it, a condenser mic would also be a nice step up for somebody with your considerable quality of writing and singing.
