I was doing a short part for a promo for my friends Ed and Ethan, and decided to have some fun with it. All four mics are through a Presonus Studio Channel Tube-Pre Amp / Compressor / Parametric EQ unit. You can get it on Amazon, HERE.
Mixer is a a Behringer XENYX X2442USB Premium 24-Input 4/2-Bus Mixer (get it HERE).
Hope this helps. Enjoy!
