Then you definitely want to get a condenser mic. And don't forget to buy a phantom power box that usually goes for about 20 bucks.
I am starting to learn that having a PA system and a mic is just not enough for vocals myself. You really need a graphic equalizer, a pre-amp, a compressor and what is called a "sonic maximizer" to get studio quality vocals.
Thank you for the information! I see I'll have to do a lot of research on some of these terms.
The condenser mic I understand though. Do you have any specific recommendations for that?
