I made the stupid mistake that so many people have made before me a couple days ago: I bought a dynamic mic, not knowing I'd need a preamp to connect it to my PC.
Now, this next bit is what I call PERFECT timing!
Just yesterday, my father came home with this little masterpiece (see picture)
Turns out you can connect your mic to this little beauty, and your PC will amplify it for you! Genius!
So, yeah, I'm pretty content with that :P
