That's the same wind sock foam I am using on my SM57 indeed!
Good to know that it will keep me "honest", if there is anything, I don't want to learn the easy way and hide my mistakes, and would like to be able to judge myself as much as possible and improve on the slightest details. I have come to the point where I can listen to myself 10 months ago, and have a big laugh

But I'm still not satisfied enough to even call myself a singer yet.. Sometimes I see singers being rejected, when I find them to sing much better than me. So my goal, is to step over that level, not sure how many years it would take.
Now, I'm not really using the mic for casual singing, but only for recording/hearing myself, it is quite difficult to get a nice compressed tone, but I guess I'm still lacking some techniques too.
Most of the times, I am on my acoustic guitar practicing scales and singing a few covers
I'll probably invest back in speakers and a mixer so I could sing trough the mic more often and hear myself directly, especially that the house is empty now, so it's a bit more comfortable
Do you think I could use my old Gallien Krueger 4x10 amp as a speaker?

It's not being used anyway... but if it can save me from buying speakers for a while..
If there is a reason why I started singing that late in my life, it's because I am not comfortable singing with someone around in the house. I think a lot of pre-singers struggle with the same issue. I usually don't gain confidence with something until I completely nail it, and to be able to do it in front of people.
It happened with playing bass, it took time and lots of practice, but at least, you can keep a bass unplugged or plug through earphones and disturb no one, and it is not as embarrassing as someone exploring their own voice.. The first few months/years can be pretty humiliating..
I found that you need to let loose and raise the volume a bit, articulate and sing with the heart, otherwise, if you're scared and want to keep a low volume, you end up straining your voice somehow, because of a fear of being "heard" and "judged".. And the singing gets surprisingly worse

It's easier to start when you're all alone, knowing that nobody else can hear and judge you (some people can be judging a**holes

)
I am guessing you're a singer? Are you a vocal coach too?
I think that today I'm ready for a vocal coach.. Just gotta find a good one.
